Reconfiguración de redes de distribución de energía eléctrica basada en optimización de mapeo media – varianza
Loor Toro, Rosanna Ximena
Resumen .- Esta investigación propone una metodología de solución basada en el algoritmo de optimización de mapeo media – varianza (MVMO), para resolver el problema de reconfiguración de redes radiales de sistemas de distribución de energía eléctrica (SDR), cuyo objetivo es determinar la combinación óptima de apertura-cierre de seccionadores en los ramales de la red que conlleva simultáneamente a un mínimo valor pérdidas de potencia activa, un perfil mejorado de voltaje, y el cumplimiento de las restricciones operativas de voltaje y topología radial. Además, de la revisión de los principios del MVMO, se evalúa su extensión, en base a preceptos de inteligencia de enjambre, a una variante denominada MVMOS, a fin de mejorar la efectividad del procedimiento de búsqueda del valor óptimo. La aplicación propuesta involucra la solución de un problema combinatorial con un espacio de búsqueda no-lineal, no convexo, y multimodal. Se implementa el algoritmo de MVMO y su variante MVMOS en el programa computacional MATLAB, para resolver el problema propuesto en un sistema prototipo ampliamente divulgado en la bibliografía especializada y que ha sido utilizado por varios autores para verificar el desempeño de otros algoritmos metaheurísticos. Abstract .- This research work introduces a methodology based on the mean-variance mapping optimization algorithm (MVMO), which is used to solve the problem of network reconfiguration of radial distribution systems (RDS) with the ultimate goal of determining the optimal combination of open/closed disconnectors that entails minimum active power losses, an enhanced voltage profile, as well as the fulfilment of operational restrictions associated to allowed nodal voltage deviations and radial topology. The rationale behind MVMO is thoroughly reviewed, and an extension, from swarm intelligence perspective, is explored in order to devise a new variant, which is termed as MVMOS, in order to attempt an improved search performance. The proposed application involves the solution of a combinatorial, with a non-linear, non-convex, and multimodal search landscape. The MVMO algorithm and its variant MVMOS are implemented in MATLAB environment in order to demonstrate and evaluate their performance by using a benchmark test system, which has been widely used in the literature for evaluating other meta-heuristic algorithms.

Cárdenas Herrera, Julio César
Resumen .- El calentamiento global es causado por el hombre debido a las emisiones de dióxido de carbono, metano y óxido nitroso fundamentalmente. Las emisiones de CO2 equivalente en el 2013 fueron de 20, 7 y 29 millones de toneladas en los sectores de la demanda, transformación y sector no energético respectivamente. Estas emisiones crecerían en el 2040 iguales a 44, 15 y 27 toneladas de CO2 equivalente para los mismos sectores indicados. Por políticas adecuadas estas emisiones podrían reducirse a 32, 12 y 10 millones de toneladas de CO2 equivalente en el 2040. Las inversiones requeridas serían de 122 mil millones de dólares en el período 2014 al 2040. Las políticas a aplicarse serían: eficiencia energética en todos los sectores, focalización y reducción paulatina de subsidios a los combustibles, reemplazo del diésel por el gas natural, mejoramiento del transporte masivo, incentivo al incremento de plantaciones y bosques, mejoramiento de rendimiento de cultivos agrícolas, procesos de cogeneración y ciclo combinado, procesos de gasificación en refinerías y biomasa, uso de energía nuclear, procesamiento de la basura y efluentes, uso de paneles solares, etiquetación de electrodomésticos, aislamientos óptimos en las construcciones, etc. Abstract .- Global warming is caused by man due mainly to carbon dioxide, methane and nitrous oxide emissions. The CO2 equivalent emissions in 2013 were 20, 7 and 29 million tons in the demand sectors, transformation and non-energy sector respectively. These emissions would grow in 2040 equal to 44, 15 and 27 tonnes of CO2 equivalent for the same sectors indicated. Appropriate policies for these emissions could be reduced to 32, 12 and 10 million tonnes of CO2 equivalent in 2040. The investments required would be 122 billion dollars in the period 2014 to 2040. Policies applied are: energy efficiency in all sectors, targeting and gradual reduction of fuel subsidies, replacement of diesel by natural gas, improving mass transit, incentive to increase plantations and forests, improving performance of agricultural crops, cogeneration and combined cycle, gasification processes in refineries and biomass, use of nuclear energy, processing of waste and effluents, use of solar panels, appliance labeling, optimal insulation in buildings, etc

Análisis de la restricción de emisiones de dioxido de carbono en el despacho óptimo de las unidades térmicas del parque generador ecuatoriano
Espinosa Gualotuña, Santiago Raúl
Resumen .- La operación económica junto con la planificación de corto plazo de los sistemas de generación, han ocupado un rol relevante en los sistemas eléctricos, ya que el operador del sistema debe afrontar la complejidad del problema del despacho económico, el cual, a más de asignar la potencia de salida específica de cada unidad generadora para abastecer la demanda horaria, debe satisfacer la función objetivo misma que corresponde generalmente a una minimización de costos del servicio, cumpliendo en todo momento las restricciones técnicas relacionadas a la operación del sistema y de cada una de las unidades de generación. Con base a lo citado, el trabajo de tesis ha permitido formular y resolver el modelo matemático de optimización para la asignación de las unidades de generación del sistema generador ecuatoriano sin considerar la red de transmisión. En este contexto, el modelo de optimización considera una función objetivo asociada a la minimización del costo del sistema eléctrico y diversas restricciones que permiten considerar las condiciones mínimas necesarias para: el abastecimiento de la demanda; las características operativas propias de cada unidad de generación térmica; y, además se ha incluido las limitaciones relacionadas a temas ambientales, es decir la cantidad de emisiones de dióxido de carbono enviadas al ambiente. Dicho problema es resuelto mediante la programación lineal entera mixta, obteniéndose así la asignación de las unidades térmicas del parque generador para el abastecimiento de la demanda del sistema eléctrico durante un período de 24 horas, el costo del sistema de generación y las emisiones de dióxido de carbono por tipo de combustible en función de las unidades de generación térmicas despachadas. Abstract .- The economic operation along with short-term planning of generation systems have played a significant role in power systems because the system operator must face the complexity of the problem of economic dispatch, which assigns specific output power each generator to supply the hourly demand at minimum cost unit, meeting the technical constraints related to the operation of the system and each of the generating units. Based on the above, the thesis has formulated and solved the mathematical model of optimization for the unit commitment of the Ecuador electrical system, regardless of the transmission network. In this context, the optimization model considers an objective function associated with minimizing the cost of the electrical system and various restrictions it possible to consider the minimum conditions necessary for: supply demand; the operational characteristics of each unit of thermal generation; and additionally has been included the environmental aspects to limit the amount of carbon dioxide sent to the atmosphere. This problem is solved by mixed integer linear programming, obtaining the assignment of thermal units generating capacity to supply the demand of the electrical system for a period of 24 hours, the cost of power generation and emissions dioxide carbon based fuel for thermal generation units involved.

Auditoría energética de las instalaciones de la empresa ecuatoriana de artefactos S.A. “ECASA”
Cárdenas Ayala, Byron Mauricio
This project performs an energy audit in “Ecuatoriana de Artefactos S.A. ECASA”, which is a factory that manufactures electrical appliances. A baseline of the current energy consumption per unit produced is identified, the opportunities for improvement are identified and the implementation of improvements with zero and low implementation costs is proposed. A verification plan for the implementation of the proposed measures is submitted. The process begins with an assessment without measurements to identify the biggest energy consumers, obtaining electricity (92%), diesel (5%), LPG (3%). Three measurements are made: the quality of electrical energy; overheating on boards; and luminance in working areas. The measurements (baseline) shown that the thermoforming, compressed air and plastic injection have the highest energy consumption per unit produced, with 39,9; 32,4 and 27,1 kWh / unit produced respectively. Energy losses due to overheating (0,214 kWh / uni), feeder losses (0,301 kWh / uni), harmonics (3,649 kWh/uni), improper shift distribution (8,88 kWh/uni), increased of production lot (3,496 kWh/uni), increased equipment efficiency (2,375 kWh/uni) and use of new technologies (25,76 kWh/uni). The total reduction is from 124,82 to 80,15 kWh/uni. The company decides to implement all improvements except the elimination of harmonics, since it requires more than $ 135,000. The total investment is $ 188,555. The annual savings are $ 74,795 and the CO2 reduction is 311 Ton.

Análisis del uso de la energía eléctrica en edificios de capacitación, caso de estudio
Simancas Vargas, Jean Carlos
In the present document the Energy Systems of SECAP Central Administration Building are analyzed. As part of this study, the point of operation of these Energy Systems is found by measuring their consumption of electric energy. With the obtained results, proposals are made for energy efficiency that allow optimize the operation of the systems making them more efficient. In this way, reduction of the electric energy consumption in the monthly invoice detail, is obtained. After that, correctives action plan are implemented, and the consumption is measured through a comparison of energy after the application of this plan. The results obtained were savings of: 1392,71 kWh / month in lighting ($115,59 per month), 16,34 kWh / day in the use of elevators ($40,68 per month), 1,69 kWh / month in main water pumps ($0,14 per month) and 8,05 kWh / month in secondary water pump ($0,67 per month). The rentability obtained using the proposals is analyzed using IRR and NPV economic indicators. For this computation, efficiency proposals were projected with a durability of 10 years, considering that SECAP will apply this action plan. Obtained results for IRR (in percentage %) and NPV (in US dollars $) respectively were: 4,34% and $5410,68 for illumination, 1,01% and $8,50 for elevators, 1,45% and $8,50 for main pumps, and finally 3,57% and $28,65 for secondary pumps.

Arévalo Llumipanta, Héctor Reynaldo
The present research presents a procedure to determine the hydropower potential that carries a natural water flow for the type that is fixed the type of turbo machine more suitable with its respective dimensioning. The process started with the study of scientific literature on worldwide research in relation to the generation of energy to establish the importance of the use of water potential in hydroelectric plants. It identifies the mechanical components, determines the parameters and the operating variables: height and flow, and fix the transfer of hydraulic energy into mechanical energy to determine the type of turbine more convenient together with its dimensioning. The study is based on detailed technical literature shown in the relevant section and studies as, for "Hydroelectric: Dimensions of social and environmental coexistence", Hydroelectric Engineering, among others; This allows generating models to find the type of Pelton, Francis and Kaplan turbine suitable for a particular application. The result of this analysis determines the type of turbine that obtains the highest percentage of energy transfer, the dimensions of the possible house of the machines; a note is given that the study is related to the possible effects of cavitation and equilibrium for a design stage.

Diseño óptimo de una red eléctrica inteligente con criterios de eficiencia energética en la demanda, a partir de la infraestructura eléctrica existente en el sector del parque bicentenario en el área de servicio de la Empresa Eléctrica Quito S.A.
Peñaherrera Sánchez, Jorge Alejandro
This research applied the methodology of Planning for Smart Grids of the University of Valencia, with the modifications and adaptations that are necessary for the technical and market conditions proper to Quito´s Electric Enterprise. In order to apply this methodology we chose the Bicentenario Park, where we implemented a proposal to improve the planning methodology in a short and medium term, with the objective of supply the demand of new technology, considering the demand management in the residential, commercial and industrial sectors. In relation to the growth projections of the demand, we created models in order to identify the degree of global penetration of the new technology, then we applied the data to the case study. In the case of induction cookers, we used the method of univariate time series and continuum. In the case of electrical vehicles we considered the international studies. Finally, in the case of distributed generation we developed a financial model. Besides, we developed stochastic profiles of the new technology, and we simulated the energy system in actual and future conditions, and using the program CYMDIST of analysis of distribution system, creating systems that obey quality conditions for each period and scenario. We added the electric and communication infrastructure to these systems, obtaining an optimum design of a smart grid for the analyzed sector. The economic model developed in the study determined the requiring cost to transform the existent grids in smart. We studied the impact due to the incorporation of new technologies in the load profiles of the primary feeders.

Estudio de las alternativas técnicas y económicas para la recuperación de calor residual en la termoeléctrica Quevedo II tomando en cuenta aspectos de mitigación del cambio climático
Haunreiter Echeverría, Benedikt
This thesis describes the possibilities of residual heat recovery in the Quevedo II thermoelectric plant. The study begins with a technological evaluation, considering the state of the art in the heat recovery in the thermoelectric generation, taking into account the quality and quantity of heat provided by the four generators considered. It was determined that two steam cycles will be applied: the conventional Rankine steam cycle with steam for the use of residual heat from the exhaust gases and a second Rankine cycle with iso butane vapor to take advantage of the evacuated heat in the condensation process of the conventional Rankine cycle and the utilization of the heat of the engines´ cooling water. The application of the two steam cycles generated a gross power increase of 292,7 kWel. Taking into account the pumps to circulate the fluid in the cycles, the net efficiency of the system increases by 3,5%. Emissions are reduced by 917,9 . The project has an internal rate of return of 10,12% in its base scenario and 20,47% if all the incentives are applied.

Construcción y modelación de un módulo didáctico de muro Trombe mediante CFD para fomentar los estudios de la calefacción solar pasiva
Torres Santos, Eduardo Rodrigo
Bucheli Naranjo, José Luis
The project presents the analysis, modeling and design of a didactic module of passive solar heating. A thermodynamic model of a wall is developed. Classical wall Trombe based on the investigation of the transfer of heat by radiation, conduction and convection of its components and using the air as a fluid. We performed a unidimensional energy balance to determine the edge conditions that parameterize the mathematical model. The results of the CFD mathematical model show the floatability and thermocirculation effects of the fluid in addition to the non-slip effect of the fluid on the surfaces and the behavior of the physical variables (density, temperature and air velocity) of the fluid in the heat transference in a passive solar heating system. In addition, we designed and built a didactic module that allows visualizing the physical behavior of the system thanks to the temperature measurement in nine different sections. The module includes the modeling of the passive heating process in time intervals for day / night by means of and the recording of temperature with variable incident radiation. The data provided by the module allow the experimental verification of the dynamical dynamic behavior of the air inside.

Desarrollo de un modelo matemático para la evaluación de los parámetros de operación de las naves en la cría de pollos de engorde
Morejón Tobar, Ramiro Eduardo
This work has been developed to study some of the effects that occur on broiler housing technology transition from natural ventilation to tunnel ventilation, in order to overcome climate impact on mass production. Air speed is the main parameter on keeping temperature lower enough to avoid chicken heat stress and dead. Due to holes and other uncontrolled air entrances, air speed drops along the broiler house. A mathematical derivation is been done to compute air speed considering a linear structural equivalent gap. This feature takes in account all unknown air entrances. The equivalent gap is used in a nonlinear mathematical model to compute the air temperature at the extractor fans which is based on the model proposed by V.F. Carvalho et all 2008 [34] whom adapted from the one develop by Louis D. Albright in his book “Environment Control for Animals and Plants”. The nonlinear model computes with MatLab each n-control volume through the velocity equation developed with the equivalent gap. Excel tools such as “Solver” had been used to determine the equation constants of the velocity expression by fitting to experimental data.. An ANSYS 2D model has been develop and validated to compare acquired data to explain some unusual air speed drops and whirlwinds. The 2D model also has shown important exponential air speed fall reducing evaporative wall efficiency.

Diseño y construcción de un dique mareomotriz didáctico y modelación del ducto de turbina
Maldonado Puente, Santiago Alberto
Oñate Amaguaña, William Paul
Currently, the increase in emissions of CO2 and greenhouse gases produced by fossil fuels requires the use of alternative energy sources, which is generated by the unevenness of the tides storing water in a reservoir through a dam to transform the hydrodynamic energy into electrical energy. This project aims to study the variables of electric generation in a turbine duct such as: pressure, velocity and turbulent kinetic energy; using a 2D computational model in ANSYS Fluent and results of experiments by constructing a tidal module for didactic purposes. The experimental results show that there are variations in pressure at the inlet and outlet of the turbine duct due to the abrupt entry and wake leaving the propellant movement at the outlet; however, the fluid remains undisturbed in the converging zone until it reaches the propellant during the entire discharge of the fluid, generating a maximum electrical power of 2.022 W. When comparing the results of the computational model with the experimental data of pressure during the discharge of the fluid in four zones of the turbine, it has an average error of 3.06%.

Análisis técnico económico, diseño y evaluación experimental de la implementación de una turbina hidrocinética para generación eléctrica
Campos Miranda, Ramiro Antonio
Vásquez, Juan Carlos
This document aims to carry out a technical and economic analysis of the implementation of a hydrokinetic turbine in an irrigation canal. It starts from an analysis of this type of turbines. The available open water channels were checked, according to its characteristics a Gorlov turbine was designed. It was dimensioned, its parameters of performance and power were revised. Two simulations were performed: one in Matlab to validate the behavior of torque and force - drag vectors; and another in Ansys to analyze the behavior of speeds, pressures and stresses in their blades. Construction alternatives were reviewed and 3D printing for blades and CAD-CAM manufacturing for the discs was chosen. The support structure was detailed and built, the turbine was assembled and transported, joined to a system of generation and load to the test site. We measured velocities, torque and power in situ and compared the actual values with those obtained in the simulations. A final evaluation of the project was performed, including: an analysis of all the costs and the value of the kilowatt hour, an analysis of its potentialities and limitations. A review of the prospects for improvement and development of this type of turbo machine was made.

It starts with a bibliographic study related to steam thermodynamic cycles in different configurations and the thermodynamic properties of water using the formulations recommended by The International Association for the Properties of Water and Steam IAPWS. The government equations, the variables and operation parameters in a certain configuration of the thermodynamic circuits are identified. This particularly allows the development of both, the mathematical arrangements with parameters that participate, and also, the information requirements to solve those arrangements. Additionally, a report is obtained with the property values of the thermodynamic states and the system thermal efficiency. The developed application can be used as a versatile and useful tool for the resolution of Rankine Cycle problems. The results obtained by using the developed thermodynamic circuit simulator are compared with their counterparts from other methodologies showing consistency. These all demonstrate the application versatility.

Metodología de diseño para una turbina Francis mediante diseño paramétrico, optimización multiobjetivo y simulación en CFD
Bone Fonte, Edwin Giovanny
The aim of this work is to develop a method that allows to obtain a preliminary parametric design of a Francis turbine runner, based on the data obtained from a hydroelectric project on flow and net head. By conducting an individual sensibility analysis on the parameters related to the erosion on the blades which allowed a better understanding on its relationship with the improvement of the efficiency and the lessening of the sediment erosion on the blades. The absolute meridional velocity of fluid, the relative velocity of the runner, blade efficiency and erosion factor were selected as objective functions for the multi-objective optimization process by means of genetic algorithms on related geometry and performing aspects. The decision variables used were the following: output diameter, flow acceleration and the degree of reaction. The work’s outcomes were the following: input and output velocities of the runner and its main dimensions. These outcomes allowed to establish an optimal way for the angle’s distribution of the blades by varying the percentage of its curvature deflection, which allows to reduce the erosion tendency. The last step of the process was the validation of the outcomes in CFD.

Identificación y separación de eventos medioambientales en el análisis de valores extremos para la proyección de periodos de retorno
Jácome Domínguez, Edwin Ángel
The present study aims at identifying and separating stochastic events according to their origin and nature in order to more rigorously fulfill the requirements of extreme value theory (EVA) and thus to obtain more robust statistical parameters. For this, wave events from the Eastern Equatorial Pacific (3 ° N, 278 ° W) were used with ERA-INTERIM database models that cover the period from 1979 to 2015. The spectral partition technique was applied to obtain independent time series. In the study area four wave systems were identified: (1) the long-distance waves of the Southern Hemisphere Storm Belt (WS1), (2) the waves from the North Pacific Ocean (WS2), (3) one more system generated from the southwest Pacific (WS3) and (4) waves produced locally due to the wind that crosses the isthmus of Panama (WS4). Subsequently to this methods for estimation of extreme values were applied: (1) initial distribution, (2) peak over threshold and (3) annual maximums, obtaining periods of return. When performing the statistical analysis of extreme values for the integrated series and individually for each of the partitioned series it is observed in this particular case that the SW1 series predominates in the extreme values of the integrated series, with the other series having less relevance. The application of EVA to independent series is more consistent, projects robust results and allows a deeper physical vision in the stochastic analysis.

Levantamiento y análisis del potencial energético aprovechable de la biomasa forestal en el cantón Riobamba y su viabilidad a través de gasificación tipo Downdraft
Orozco Cantos, Lenin Santiago
The present study indicates the location and quantification of forest biomass available for energy use that is obtained from the lumber sector of the canton Riobamba to determine the energy value that they represent in the local environment and to be transformed into a gaseous fuel by means of gasification downdraft allocating its calorific value to the thermal or electric generation. The survey of biomass data is obtained through a census to all establishments that work with wood, dividing the area surveyed into 35 sectors, 24 urban and 11 rural, depending on the population density. For the energy transformation the gasification equipment at ESPOCH is used and an experimental stage reveals the actual parameters of the gasification process and characteristics of the fuel gas, whereby the technical and economic values of generation for thermal or electrical uses can be determined. The amount of forest biomass generated in the canton is 61.21 tons, which have different purposes and economic influence, the percentage that can be used for energy uses is 17.37%, which represents 39.34 MWh. The cold efficiency of the gasification equipment with the improvements implemented and the quality of the gas generated are close to the theoretical reference parameters, 72.28% and 5.198 MJ/kg correspondingly. The cost of thermal generation in substitution for LPG is favorable when compared to an international cost, while for electric purposes the value of kWh is even higher than the sales price indicated by CONELEC.

Estudio de la influencia del factor de forma sobre la temperatura operativa de edificaciones en la ciudad de Quito, mediante simulación en EnergyPlus
Cárdenas Ramos, Edwin Javier
Fernández Jiménez, Daniel Efraín
This study aims to determine the influence of the shape factor over the thermal behavior of residential buildings in the city of Quito, through energy simulation in EnergyPlus. The thermal behavior will be evaluated with the operative temperature and as an objective function the thermal discomfort. According to the ASHRAE 55 regulation, the comfort range for the city of Quito is established and is evaluated in single-zone and multizonal scenarios through statistical analysis of operative temperatures for residential buildings based on discomfort. For the monozonal modeling, two analyzes are established, in the first one it is determined that the geometrical shape of the building (square, rectangular, form L and form U) and the form factor do not have a significant impact in relation to the operative temperature and discomfort of the buildings; and, in the second, it is evident that the influence of the shape factor on the objective function (discomfort) is given by the incidence of solar radiation on the building surfaces that have a greater area exposed to the West-East. In the multizonal case, the modeling of a rectangular building with five internal zones is performed, in this analysis it is determined that the shape factor has a low incidence in the thermal behavior of the building and that the conditions of edge, orientation and glazing of the building have a greater influence on the comfort and internal operative temperature of the building.

Estudio e implementación del punto triple del mercurio en la calibración de instrumentos que miden la magnitud temperatura
Paucar Quinteros, William David
The purpose of the present research was to study the Mercury triple point (TP-Hg) defined in the International Temperature Scale of 1990 (ITS-90) for the Standard Platinum Resistance Thermometers calibration. The definition and development of this triple point are used to stablish a primary standard of temperature in the National Metrology Laboratory of Ecuador. In addition, it allows improving calibration and measurement capabilities of the laboratory to future declaration and registration in the key comparison database of the International Bureau of Weights and Measures (BIPM). The Hg TP was measured in two different methods, such as, freezing and melting. Each phenomenon was reproduced with an ISOTECH Mercury cell of 99.99999% purity, a high stability maintenance bath, a Quartz-Sheath SPRT, and a high uniformity and accuracy thermometric bridge. Furthermore, the group of listed equipment has traceability with the National Institute of Standards and Technology (NIST-EEUU). The data repeatability and reproducibility of the research measurements was calculated with the ANOVA accuracy method from the standard ISO 5725-2. The physic model was stablished. This model considers suppositions about the measuring and relevant physical variables. The model was represented according to a mathematical language where the countable uncertainty forces are determined. Also, the freedom degrees were chosen to stablish a level of trust that let obtain the expanded uncertainty associated with this measurement.

Estudio y análisis del grado de contaminación lumínica en un polígono (o área) del sector norte de la ciudad de Quito de acuerdo a la normativa de polución lumínica mundial – propuestas de solución
Silva Sánchez, Willan Fermín
This project is focused on the determination of the light pollution level in a polygon located in the north of the city of Quito by using a night sky quality meter. The average value measured is 15.2 mag/arc*s². If a sky without light pollution has a value greater than or equal to 22 mag/arc*s², it is concluded that the sector under study has a high degree of light pollution. This work shows the possible reasons that caused the light pollution and the solutions to reduce the effects result of this phenomenon. In order to know if the light pollution is directly related to the excessive consumption of energy, we proceeded to determine the energy rating of the roads that are in the polygon under study. The results show that the street N3 Cap. Ramón Borja has an “F” rating corresponding to an inefficient energy consuming street. Finally, this project proposes solutions to reduce the degree of light pollution.

Estudio Paramétrico para Optimización del Generador de Hielo Tubular del Laboratorio de Energía de la Escuela de Ingeniería Mecánica – ESPOCH
Guapulema Maygualema, Rocío Paola
The main objective of the thesis is an optimization of the ice tube generator of Energy Laboratory of Mechanical Engineering School at ESPOCH University based on a parametric study. For that, the main parameters involved in the ice formation and thermal energy storage were studied, which are: water storage temperature, refrigerant temperature in the evaporator and condenser, ice subcooling temperature and ice formation speed. Two outstanding parameters that intervened in the ice formation process were the environmental conditions of the place and the water temperature used, it was observed that by decreasing the environmental temperature, the thermal load decreases and the efficiency of the condenser improves, which directly influences the efficiency of the team; when the environmental temperatures decrease, decreasing the thermal load and improving the efficiency of the condenser, which directly influences the efficiency of the equipment. The instability observed in the first hour of experience intervenes in the final water temperature, final temperature ranges from 1.1 ° C to -0.4 ° C in three hours for each experience made.

Diseño y caracterización de un material compuesto por roca volcánica y concreto como material alternativo de construcción que permita mejorar los niveles de confort interno en viviendas localizados en climas fríos
Pachacama Morocho, Ramón Edison
Obando Velásquez, Juan Neptalí
At the local level and especially in the urban area, the most used construction material is the concrete block, however, the thermal insulation capacity of this type of material has not been considered. Considering this problematic, we have proposed the present study, which consists of elaborating blocks for masonry, composed of sand of volcanic rock (traquiandesita), gravel (relation 20 - 80) and concrete, as alternative material of low cost, high thermal isolation and easy to elaborate for the native settlers of these zones. For the project the mixture was elaborated of concrete based on the standard ACI 211.1 and ASTM C33, where the procedure is established to optimize the granulometry in the mixtures of concrete. The thermal properties of the material were evaluated measuring the heat conduction across a massive hollow cylinder in stationary regime, and in transitory regime using the equipment KD2 Pro based on the method of thermal needle. The results obtained experimentally by mechanical tests of compression, of thermal conductivity (k=0.1404 W/m. K) and thermal resistance (9.09 m2. K/W), verify that the alternative block can be used for sake of thermal isolation and improvement of the domiciliary comfort.

Obtención de un biocombustible sólido por torrefacción húmeda a partir de la cáscara de la mazorca de cacao para la generación de energía
Cayo Reinoso, Eduardo Luis
Se realizó la caracterización energética de la cascara de la mazorca de cacao (CC). La CC posee un contenido de humedad del 85,1%, material volátil del 66,8%, contenido de cenizas del 8,9%, carbón fijo del 24,3%, un contenido de carbón elemental del 45,3%, hidrógeno del 5,5% y oxígeno del 39,4%. El poder calórico superior (PCS) en base seca fue de 18,2 MJ/kg. Luego, se estudió el efecto de la temperatura y tiempo de residencia sobre las propiedades del biocombustible sólido. Como resultado de este estudio se obtuvo que la temperatura tiene un efecto estadísticamente significativo sobre el contenido de material volátil, carbón fijo, cenizas y naturaleza hidrofóbica; mientras que el tiempo de residencia, la temperatura y la interacción entre estas dos variables tuvieron un efecto estadísticamente significativo sobre el PCS, rendimiento másico y energético. Además, se estudió el efecto de la recirculación del agua de proceso sobre las propiedades del biocombustible. Se obtuvo que la recirculación del agua tiene un efecto estadísticamente significativo sobre el contenido cenizas, naturaleza hidrofóbica, PCS y rendimiento energético. También, se determinó que la energía que se necesita para la obtención del biocombustibles en el laboratorio es mucho mayor a la energía bruta que puede suministrar el mismo. De igual manera, se encontró que la producción del biocombustible en el laboratorio demanda un costo de 6 a 16 veces más que el costo de venta del mismo. Por último se simuló en el software ASPEN PLUS® versión educativa el proceso de torrefacción húmeda. Los resultados de la simulación mostraron que si se trabaja en un reactor continuo y se recupera el calor contenido en la fase líquida y gaseosa del proceso, la torrefacción húmeda es energéticamente viable.

Planeación energética en la implementación de un sistema normalizado de gestión de energía en la planta industrial Palmeras de los Andes
Rosero Rivera, Pablo Vinicio
The objective of this work was to carry out the energy planning phase as part of the implementation of a standardized energy management system at the Palmeras de los Andes industrial plant from Quinindé Canton. The methodology used for this analysis follows the requirements of the Ecuadorian Technical Standard NTE INEN-ISO 50001: 2011. Information was collected from 2016 regarding the company's consumption of electricity, diesel and biomass, as well as its monthly palm oil production, which identified a potential for 10% electricity savings. An inventory was made of the electric motors used in each production process to quantify their electricity consumption where palmisteria, extraction, boilers and clarification are the main consumers. Finally, among the main opportunities for improvement identified are the recovery of condensates from palmisteria, the replacement of thermal insulation in sterilizers and the increase of self-generation of turbo steam electric power to replace 83% of electricity in the public service. Consequently, for the palm sector with the voluntary adoption of Standard 50001 and the implementation of opportunities for improvement could achieve monetary savings approaching USD 1,560,000 per year.

Acoplamiento de un sistema neumático con regeneración a una bicicleta de ciudad
Chávez Guevara, Andrés Vladimir
The population growth of Quito city in the latest years carries to a mobility problem of the people who live in it at present. This job aims to the use of the bicycle as a mobility way and incorporate a pneumatic system that together with other subsystems regenerate the excessive energy involved in a descent and subsequently it makes the energy useful in an ascend, reducing the user effort. The pneumatic system has a control subsystem, which manages the available energy saved in the reservoir. Bicycle tests were evaluated according to the processes of regeneration and drive, being implicit the evaluation of the control system. The regeneration process is possible in agreement with the tests. Because of the fact that the pneumatic system has a reservoir, it was established that it can be charged by means of an external source (fuel station, vulcanizer, etc.). For this reason, the drive process was performed with the energy stored by regeneration and with the energy provided by means of external source. In conclusion, the pneumatic system can extend the bicycle use to users that, for any reason, shouldn’t do much effort.

Diseño paramétrico, optimización multiobjetivo y simulación CFD de una bomba funcionando como turbina para la generación eléctrica a partir de un canal de riego
Sánchez Pruna, Jorge Eduardo
The objective of present document is to establish parametric design of a pump impeller operating in turbine mode (PAT), based on characteristics of source for hydroelectric generation (flow and net height); same that currently supplies an irrigation system in Cotopaxi province. Civil works were determined based on water flow and height. Water flow which was obtained through general duration curve (CDG), and height is function of place’s topography. In micro and mini hydroelectric projects, a flow that is 90% of time is recommended, however geometric differences using Q-90% flow rate or a larger one Q-30% are minimal and their influence is low on project’s total cost. In this sense flow rate (Q-30%) was chosen. Within multiobjective optimization process through genetic algorithms, impeller’s speed and width at exit of it, erosion factor, as well as efficiency were selected, as objective functions. Decision variables are impeller diameter and impeller’s angle of exit, and number of blades. Process ends with results validation in CFD.

Diseño, construcción de un sistema de producción de energía eléctrica para la generación de 800 W a través del uso de biogás, para una pequeña granja y análisis energético del sistema
Cusi Sacansela, Juan Esteban
The present study exposes the design and selection of the elements for the construction of an electric generation system that uses the resource the biogas that is produced through the manure of cattle. The process began with the characterization of the study of cattle in the laboratory of the National Institute of Agricultural Research INIAP, the results presented a carbon nitrogen ratio of 22,80 that generated a greater speed of biodegradation of the raw material and production of biogas. After the mixture of manure and water in a hermetically sealed batch-type biodigester biogas was obtained during a retention time of 35 days, which was carried out the chromatography analysis in the Instrumental Analysis laboratory of the EPN Chemical Engineering Department to check the state of purity of the methane that is the main element as a source of fuel. In the tests carried out on the generation of biogas, it was proved that a volume of 0.72 m3 of biogas was obtained in the aforementioned time. The entire process of selecting the necessary elements for the construction and the whole system of electric power generation was carried out through analytical and systematic methods. The biogas consumption for a load of 120 W was 1.05 m3/h in a test time of 10 minutes and an efficiency of the electric power generation system of 20%. The investment made in the project that has been executed is detailed.

Estudio prospectivo del sector transporte de Ecuador y su incidencia en la matriz energética en el periodo 2017 - 2040
Barreiro Hidalgo, César Mauricio
A prospective study of the transport sector of Ecuador has been developed, and its incidence on the energy matrix in the period 2017 - 2040, so as to evaluate various scenarios that allow the adequate use of the energy resources available in the country, In addition, to reduce the emission of gases greenhouse effect in the transport sector and reduce imports of fossil fuels. The relationships between the different elements that structure the energy matrix of the transport sector and its effect on the economy, environment and society were analyzed. For this, different scenarios were proposed, that served to evaluate the transport sector. Pilot projects were proposed in the group of rental vehicles for the replacement of traditional vehicles with internal combustion by electric vehicles, taking advantage of the installed capacity of the country's hydroelectric projects. The potential offered by the partial substitution of fossil fuels for biofuels, such as the ecopaís® gasoline, is also evaluated. Projecting scenarios of increasing the percentage of bioethanol from 5% to 10% in the medium term and the introduction of biodiesel for the group of cargo vehicles. To conclude, the scenario that presents the greatest benefit to the fossil fuel economy is the introduction of electric vehicle technology.

Elaboración de una propuesta de un plan de desarrollo energéticamente eficiente y de bajas emisiones para el sector de transporte de pasajeros en la Ciudad de Quito
García Lucero, Fabio Humberto
The present work proposes an energy efficient and low emission development plan for the transport of passengers in the City of Quito, using transport modalities, which enable energy saving, reduction of greenhouse gas emissions (GHGs) and savings economic for Ecuador. For this purpose, a prospective study was carried out for the period 2015 -2035, where three scenarios of evolution of the Sector were analyzed: one trend, with the participation of the transport modalities present in the base year; and two alternatives where energy efficiency measures were simulated with different intensity, such as: public transport electric systems such as the "Metro de Quito", 100% electric buses, electric taxis and the urban cable car; the overcrowding of the use of hybrid and 100% electric private vehicles and the greater penetration of conventional low power cars. The study was complemented with a sensitivity scenario regarding the penetration of biogasoline "Ecopaís" (mixture of gasoline and ethanol). As a result of the simulation, energy, environmental and economic indicators were obtained for each of the scenarios, based on which the proposal for the development plan of the Sector was structured for the study period.

Diseño y construcción de un sistema de compensación reactiva para reducción del consumo de combustible diésel en la generación térmica de la Isla San Cristóbal Galápagos.
Santander Ortega, Milton Aníbal
The generation system on San Cristóbal Island is a hybrid system composed of thermal and wind generators. The objective was to reduce diesel consumption from two well-defined actions, the first involves the automation of the current SCADA and control systems to improve the joint operation between thermal engines and wind turbines, based mainly on an energy analysis that optimizes the control of active and reactive power; The second action was the construction of a system of compensation of reactive energy that allows to compensate the imbalances of reactive energy caused by the variations of the wind, as well as to compensate the thermal generators so that their reactive power is zero. A first stage evaluates the current situation of the generation system, selecting the best technological option to be applied in the generation system. A second stage involves all the necessary calculations for the design of the chosen compensation system and the construction of the system was carried out, adapting it to the current generation system. Finally, operational tests were carried out on the generation system of the island, measurements were obtained in the field and the results were analyzed.

Alternativas para el aprovechamiento energético en los motores Waukesha a gas del CPF bloque 15 Petroamazonas y análisis exergético correspondiente
Caizaluisa Casa, Guido Renato
Mollocana Jácome, Guillermo Saúl
This project determined the thermal balance of the motor Waukesha model VHP L7042 GSI that uses associated petroleum gas as fuel in the block 15 location of Petroamazonas EP. Based on the available thermal energy, it was developed proposals for the use of these energy residues in order to increase energy efficiency in fuel consumption. The available thermal energy in the exhaust gas would be used in a heat exchanger, in which water is heated. After, this water is used to heat crude oil, as part of the required petroleum production dehydration process. The exchangers replaced a water-heating furnace which uses associated gas to take advantage of this fuel in electrical generation by optimizing gas consumption. The thermal energy available in the cooling water jacket is used as a heat source for the operation of the absorption refrigeration equipment, which is proposed to replace 112 units of individual air conditioning systems. The cost-benefit analysis of the selected proposals justifies them as feasible projects with a return of the high initial investment in the medium term. This project helped to optimize the non-renewable resource gas and electric energy obtaining significant economic savings for the company and also minimizing emissions to the environment giving a contribution against the global warming problem.

Diseño y construcción de un prototipo para el seguimiento del punto de máxima potencia con el uso de paneles fotovoltaicos orientado a embarcaciones
Rivera Liger, Carlos Germánico
Autonomous photovoltaic systems have a control unit for charging the batteries. The most advanced control units are able to follow the point of maximum power of the photovoltaic generator (MPPT, for its acronym in English). However, in the case of vessels it has been proven that this tracking capacity is disturbed by the movement of the vessel itself. To analyze and see how this phenomenon can be corrected, this project has designed and built a battery charge controller for the photovoltaic system of the scale model of a boat. For this purpose, a small photovoltaic system has been designed with a 5W and 12V panel, a 1300 mAh and 12V battery.
To control the voltage and current to the load (the battery), the controller has a DC / DC reducer converter in the Buck type reducer type to operate in continuous operation mode. The tracking of the maximum power point basically consists in finding the correct impedance called Optimum resistance or Optimal conductance, varying the useful cycle of the converter by means of the algorithm of incremental conductance control. An ATMEGA328p microcontroller executes the algorithm programmed for the battery charging stages.

Análisis de eficiencia energética en combustibles para sistemas de generación eléctrica aislada en las plataformas de pozos de producción de crudo 420, 470 y 480 en el Campo Sacha - Bloque 60. Análisis técnico – económico
Garcés Poveda, Diego Sebastián
In this present work an energy efficiency analysis of fuels of the three production platforms of crude PAD 420, 470 and 480 was carried out in the Sacha field - Block 60, since at the present time there exists own and rented electricity generation that uses diesel as fuel for the operation of bottom equipment. The operation cost is 10,000 USD a day for the three PADs. These platforms have surface facilities to separate natural gas and burn it in lighters with the aim of not having problems in the pumps at the moment of the crude oil transference to the stations. By means of the methodology, ten-year data was obtained on volume of natural gas of the platforms, as well as on the main components for the use of an equipment that meets these conditions. As an experimental part, gas chromatography analyses were carried out on each platform to analyze its fuel components, as well as the net power for electricity generation required by the bottom and surface equipment. Ecuadorian companies presented offers for the current conditions of each platform where there are Bi fuel equipment, turbines and gas engines. Therefore, a technical-economic analysis of the current costs was carried out: (PAD 420: $ 0,17 kWh; PAD 470: $ 0,17 kWh; PAD 480: $ 0,13 kWh) and applying the investment of new technologies, it would be: (PAD 420: $ 0,046 kWh; PAD 470: $ 0,061 kWh; PAD 480: $ 0,10 kWh), reducing to 4.000 USD a day

Desarrollo de guía metodológica para el manejo de alternativas eficientes de climatización en edificaciones ocupando las potencialidades de ahorro en la sierra ecuatoriana. Caso de estudio: Edificio Plaza 2000
Calderón Montalvo, Andrés Roberto
The present work begins with a study regarding the history of air conditioning and its most basic definitions considering the measurements and equipment required; likewise, the study specifically exposes the foundation on which the criteria of air conditioning are based, addressing issues about the thermodynamic properties of the air and its behavior with respect to outdoor conditions, humidity control among others. The study of the thermal load, after a brief explanation of some methods and after assessing their functionality is done based on the methodology of the difference in cooling load temperature. The method called cooling load temperature difference (CLTD / SCL) is approached in the most practical way by studying the heat gain in the Plaza 2000 building located in the Ecuadorian highlands, this case allows us to approach a practical example, which set out the main parameters to be considered in an efficient air conditioning design considering the savings potential, which can be understood from the parameters used for the development of results in this method. Finally, the difference between the thermal load of the block and the electrical load for the transformer that feeds the building is exposed, quantifying and differentiating these two properties. So that the guide reaches the exposition of the practical methodology for the study of the load and can serve as support for a practical review of installed air conditioning systems or in-depth studies to be carried out.

Estudio de estrategias para la inserción de vehículos eléctricos tipo taxi en la ciudad de Quito
Bastidas Auquilla, Byron Wilfrido
This paper proposes strategies for the insertion of electric cabs for the transport of passengers in the city of Quito. The strategies are based on the analysis of the information provided by a study sample and the experience of different cities around the world, which have been successful in the insertion of electric vehicles. The necessary information was obtained through bibliographic review, surveys, records and data from global positioning systems (GPS). Through the processing and systematization of the information, the study focused on the service of cabs according to the typical operating conditions. The main parameters analyzed were investment costs, operation and maintenance, autonomy, energy consumption, emissions, advantages and disadvantages of the use of electric vehicles as cabs and strategic locations of charging stations. According to the results obtained, it is concluded that the insertion of electric cabs in the urban area of the city of Quito is viable with the implementation of fundamental strategies such as: establishment of standards and regulations, exception of import and customs taxes for electric vehicles, spare parts and batteries, government and local incentives for the purchase of electric vehicles and replacement batteries, charges reduction for vehicles registration, preferred rates for electric bills, bonus for the non-emission of greenhouse gases (GHG) and public charging infrastructure.

Diseño de un sistema de cogeneración asociado a la central de generación eléctrica del bloque 18 de PETROAMAZONAS EP
Rodríguez Paspuel, Edison Fernando
The growing global awareness of the efficient use of energy resources has forced governments to re-examine their energy policies and take measures to avoid wasting them. Our country is not the exception with the creation, according to Decree No.1048, of the "National Institute of Energy Efficiency and Renewable Energies", so the present thesis project is in order with this trend of national and global awareness, within a framework of protection to the environment; having as objective to propose a viable economic technical alternative to recover the thermal energy rejected in the form of heat through the exhaust gases of the three (3) Wartsila gensets W16V32 of the Generation Plant (PGE) located in the base ZPF of block 18 of Petroamazonas EP. It will begin by performing an exergy analysis of the exhaust gases of the Wartsila units, to determine the useful work potential that can be obtained from the heat coming from this heat source. Then the thermodynamic design of a HRSG (Heat Recovery Steam Generator) and its support systems, which would recover heat from the exhaust gases of Wartsila units. With the implementation of the proposed system, considering a 95% availability, it will be able to generate a power of 1621 kW and an average annual energy of 1'108.764 kW.h

Estudio técnico económico para aprovechar los gases de escape en el enfriamiento del aire de entrada al Compresor de las Turbinas de gas Solar Centauro 50 de la Planta de generación TPP
Ramírez Jácome, Milton Ernesto
Noroña Núñez, Ronal Marcelo
The Centaur 50 (C50) gas turbine nominal power output (4,4 Mw) is limited by its inlet air temperature, when it is increased also increases the temperature of the combustion chamber until the alarm or unscheduled stop condition is reached , to ensure that the above condition does not occur, the power delivered by the generation set must be reduced. To avoid this power loss, the current study aims to use the exhaust gases in a cooling system and reduce the inlet air temperature until the standard condition. The study development begins with some theoretical concepts related to the topic, it continues with the methodology used to obtain the current condition operation parameters, the work place environmental conditions and the inlet air reference conditions. These values allow us to select the components of the air-cooling system, calculate the efficiency parameters corrected at the reference temperature, and determine the project economic indicators. The obtained results shown, that by cooling the inlet air, the electric generator power output increases by 14,38 %, the heat rate decreases by 3,71 % and the thermal performance reaches 34,32 % approximately. The economic indicators show that this project is technically and economically feasible to be implemented.

Ubicación óptima de generación distribuida en redes de distribución usando programación no lineal entera mixta
Carvajal Proaño, Andrés Francisco
The main objective of this investigation is to determine the finest location of distributed generation in an electrical distribution system at a main feeders’ level through the resolution of a mixed integer non-linear programming model, which is resolve by means of the GAMS computational tool. The mixed integer nonlinear mathematical programming model will be applied to a 33-bar IEEE distribution system, which will determine the optimal location of the GD. In order to do this, the inherent characteristics to perform the operation of electrical systems will be consider into play. In this scenario, a comparative analysis will be perform with a commercial software for the simulation of electrical systems – ETAP. This system will allow simulating the IEEE system and calculate the results of the proposed mathematical model. Once the mathematical model is evaluated, four study cases will be generated, in which different amounts of GD are integrated. In these cases, technical variables are calculate it, such as voltage level, losses, among other significant aspects. These will allow us to conclude that the mixed integer non-linear programming model makes it possible to find the optimal location of several GD units in the network, guaranteeing the technical conditions of the network and fulfilling the objective of minimizing losses in the system.
