Análise técnica para implementação de reconfiguração automática de alimentadores de distribuição com sistema Self Healing

Abstract

The present work has the objective of evaluating a technique of automatic reconfiguration of distribution feeders called Self-Healing through the hypothetical substitution of conventional switching and disconnection equipment by automatic reclosers configured with Loop-Scheme logic in urban distribution feeders. Feeder reconfiguration systems are compared in the conventional way, through maintenance teams that operate equipment manually, with automatic reconfiguration, after equipment replacement. The demonstration is performed in two real urban distribution feeders, sectioned with a number of consumers, in which faults are simulated and the steps performed in the system for the replenishment of the feeders and the isolation of the missing section are demonstrated. The steps of analysis of power flow, short circuit, coordination between reclosers installed in series and at the end are demonstrated the reduction values of the DEC indicator obtained for the system under analysis after the implementation of the reconfiguration system.
