Operación del sistema de potencia a escala del laboratorio físico de sistemas eléctricos de potencia : operación en paralelo del generador fotovoltaico con la red eléctrica de la EEQ.

Abstract

This project deals with the operation of the Photovoltaic Generator of the Physical Laboratory of Electrical Power Systems in isolation and connected in parallel to the electrical grid of Empresa Eléctrica Quito. First, the four power generation modules are analyzed, followed by a detailed description of the photovoltaic generator. In the photovoltaic generator, the physical components are studied as well as the software, the former focuses on the power inverter and the elements that compose it, such as sensors, protections and others. The software focuses on the TMS320F28377S card from Texas Instrument. The control system is developed on this board and through the use of measurements obtained by means of voltage and current sensors in alternating and direct current. To determine the feasibility of parallel operation of the photovoltaic system, a study of the operating limits of the photovoltaic generator is carried out, as well as a procedure for the correct parallel operation of the two energy sources. In order to verify that the system is working properly, operation tests are performed in parallel with the electrical network and tests are performed operating the generator in isolation, feeding loads and obtaining values of voltages, currents and injected power, the results of which are shown in the figures.
