Avaliação da perda de coordenação na proteção de um sistema de distribuição na presença de fontes de geração distribuída

Abstract

Installations of solar modules in homes, buildings and industrial areas are growing. These distributed generation sources may end up causing problems in the utility's electricity distribution system, which may cause overload of transformers. The objective of this work is to demonstrate that distribution system protection coordination as selectivity is possible even with distributed generation, analyzing fuses and reclosers. A simulation of a specific chosen case, IEEE 13 Bus system, was carried out. For the analysis of the system, the Power World simulation software was used. Through the analysis and simulation in the software, it can be evaluated that, for the IEEE13 Bus systems, it is possible to maintain the coordination between the fuse and reclosers.
