ESTUDO DE IMPLANTAÇÃO E QUALIDADE DE ENERGIA ELÉTRICA DO SISTEMA DE MICROGERAÇÃO FOTOVOLTAICA NA REDE DE BAIXA TENSÃO

Abstract

With increasing urbanization, more and more consumer units are connected to energy distribution systems. With the emergence of distributed generation, consumer units have become generating units, thus the concern with the quality of the system’s energy has become crucial. In this way, this work develops the necessary steps for the implementation of the photovoltaic distributed generation system with the distribution concessionaire, analyzing the steps for the homologation of the system in the ENEL-GO distribution network, focusing on the quality of electric energy. Therefore, the general objective of the work is to guide the homologation and installation of the photovoltaic distributed microgeneration system and to verify if, after the connection with the distribution grid, the energy quality parameters outlined in module 8 of the Electricity Distribution Procedures (PRODIST) are maintained. At work, the approval stages involve: i) documentation, ii) project submission, iii) system installation, iv) inspection, and v) power quality. System data are collected using an energy analyzer in a sampling campaign of 7 consecutive days, with a 10-minute interval between each reading, totaling 1008 readings. As a result, the methodologies used in approval, installation and analysis of energy quality were satisfactory, as evidenced by the approval of the access report and the inspection carried out by the concessionaire. In addition, all data collected by the energy analyzer demonstrated that the system parameters are in compliance with PRODIST module 8.
