Implementación de un sistema solar fotovoltaico de 4 KWP y diseño de un sistema de control y monitoreo para el edificio de robótica de la FIE.

Abstract

The objective of this research project was to implement a solar photovoltaic system (SFS), as well as the study of an applicable control system for a self-consumption station in the Escuela Superior Politécnica de Chimborazo (ESPOCH) in the Faculty of Informatics and Electronics (FIE). This system was planned to supply lighting loads only. The system's implementation comprises sixteen solar panels, a charge controller, an inverter and a STUDER brand communication card, and a bank of four batteries and protection equipment. For the correct use of the equipment mentioned above, a simulation control system was carried out using MATLAB and Simulink software, having Fuzzy control as a methodology to optimize the system instructions. The capacity of the photovoltaic generation system is 4 KWP; due to the restrictions of the equipment, load supply studies were carried out with the output power limitation instructions and a set of loads that add up to 750W. It was determined to compare the pre-established control in the acquired equipment with the control carried out in simulation and implemented in the solar system. The comparison showed that, when changing the charge current setpoint to the default control system, several of the setpoints were similar and, as an advantage of the control, allows improving the batteries' autonomy. It is concluded that the maximum power point tracking (MPPT) works according to the loads being supplied. The system has a monitoring system that allows the user to interact with the operating instructions and to be modified according to the needs of the simulation model.
