COORDINACIÓN DE LAS PROTECCIONES DE LA SUBESTACIÓN DE DISTRIBUCIÓN EN EL SISTEMA MILAGRO GUAYAS – LOS RÍOS

Abstract

This paper develops the study of the coordination of protections applied to the distribution substation "MILAGRO SUR", located at Milagro city. Starting first from the description of the facilities, for the elements that compose it, then a load flow study is performed at maximum and minimum load and a short study applied to the substation bars of 69kV and 13.8 kV, this will serve as preliminary data to proceed with appropriate adjustment of substation protection and coordination thereof with protection of the distribution system, by using modern tools we will get the best option in terms of coordination protections allowing to increase reliability and system performance to any fault conditions.
