Aplicação de sistema self-healing em redes de distribuição de energia elétrica.

Abstract

This work presents an analysis to reduce the time of interruption of energy for consumers of electric energy, optimizing the indicators of the service provided by the local utility, improving the reliability of the system and ensuring continuity in supply to the largest number of customers possible through of the implantation of Self-Healing systems in the distribution network by means of reclosers remotely in medium voltage networks. The study consists of defining primary networks to receive the systems of Self-Healing based on the performance and impact that they cause in the indicators considering the amount of consumer units reached as well as critical loads, as well as to analyze the available communication protocols that provide reliability and low cost for automation, in addition to developing a computational algorithm for missing section isolation and recomposition of electric power distribution networks based on the concept of smartgrids. The Self-Healing system consists of detecting a fault in a given section of the distribution network and returning maneuver plans containing allowable operating configurations for isolating the affected circuit stretch, and automatically reconfiguring the network in order to restore the power supply to a part of the affected loads, considering operating restrictions and loading of network components in order to guarantee system integrity, power quality and evaluate the new coordination of system protection after load transfer.
