Estudo comparativo de métodos de localização de curto-circuitos em redes de distribuição de energia

Abstract

In this dissertation, a comparison is proposed between different algorithms for locating permanent faults in power distribution networks. The aim is to obtain parameters that can guide power companies on the best results found in order to be used in real applications, achieving the best cost­benefit in the fault location process. Simulations of faults will be carried out using the ATP (Alternative Transient Program) and Matlab® software. To validate the knowledge acquired during the electrical engineering course, the computational implementation and comparison were performed using two fault location methods: voltage sags and apparent impedance. The simulation was conducted on a real feeder with 134 buses, where faults with different impedances were placed at different points in the network, allowing for comparison of the location rate in different situations for both methods.
