Uso de religadores automáticos como otimizador dos indicadores de qualidade da rede de distribuição

Abstract

Electricity distribution concessionaires continually seek ways to reduce the frequency and duration of interruptions in the supply of electricity to their consumers, aiming to promote consumer satisfaction and compliance with the regulations of the National Electric Energy Agency (ANEEL). Some of the measures adopted to improve the continuity of the energy supply are the replacement of fuse switches, overcurrent protection equipment incapable of differentiating transient faults and permanent faults, with automatic reclosers, equipment that automatically opens and re-energizes the circuit in case of transient fault. This work presents a comparison of data on the frequency and duration of supply interruptions in a region of the Equatorial Alagoas distributor, before and after the installation of automatic reclosers in the distribution network, to evaluate the impact of the implementation of this equipment on collective continuity indicators. DEC and FEC. The data shows that replacing a recloser fuse with an automatic recloser reduced the DEC and FEC values by 51% and 65%, respectively, while replacing a fuse with an automatic recloser reduced the DEC and FEC values to 0. FEC, showing the potential of using reclosers as a means of improving the continuity of electrical energy supply.
