Asignación de caídas de voltaje por zonas en el área de servicio de la Empresa Eléctrica Quito

Abstract

The Emprea Electrica Quito does not have a theoretical basis for the assignment of voltage drops in the elements of the Distribution System network, to determine the permissible voltage drop limits. When analyzing the CONELEC 004/01 regulation in which it is based on voltage drop limits, they are not in accordance with the ANSI C84.1 Standard which is the construction of equipment and household appliances of the users. To carry out the present study, divide the concession area of the EEQ into 3 zones according to their present demand density in micro-areas. The compilation and verification of the information provided by the EEQ corresponds to the measurements made in the food manufacturers' headings in the criteria of voltage and demand level; for distribution transformers a study is taken into account the nearest and farthest from the primary feeder, to load a model in the secondary circuits are taken the energy averages during the period 1 year of customer billing, with all information before detailing simulations are performed on each element of the network to determine the voltage drop. The voltage drops of each of the elements of the distribution system are determined by simulations in the CYMDIST software; with the obtained results, the average voltage drop and the most critical by the zone are compared; from this the supply of voltage drop assignment is elaborated according to the necessity of each zone framed in the ANSI C84.1 standard.
