Impacto da Geração Distribuída por Fonte Fotovoltaica em uma Rede de Distribuição e seu Sistema de Proteção de Sobrecorrente

Abstract

The different peculiarities of distribution systems added to the variability of generation and integration by sources of distributed generation, bring with them challenges for the adaptation of the entire network and, mainly, for its protection systems. In this context, this work analyzes the impacts caused to the protection system of a distribution network after the integration of distributed generation by photovoltaic solar source against different test scenarios for the insertion of distributed generation and the occurrence of faults. The results demonstrate the influence of the variability of the integration of distributed generation on the voltage profile of the distribution system and on the protection actuation depending on the location of the generation source, the fault location and positioning of the relays. reverse fault and consequently non-compliance with the basic requirements of the protection system.
