Coordinación de protecciones de los alimentadores primarios a 13,8 kV de la S/E Pujilí para la Empresa Eléctrica Provincial Cotopaxi

Abstract

The study provides the protection coordination of primary feeders, named Pujilí Centro and Pujilí Zumbahua, supplying energy to Pujilí, based on an analysis of the technical and electrical characteristic of the feeders in study, describes the methodology used for coordination between each element and protective equipment installed throughout the system, and the types of faults to which they are exposed. Studies of power flow and short circuit currents required for the study were performed using computer programs CYMDIST and CYMTCC, resulting in a reliable, sensitive, selective and fast protection, in the presence of faults; reducing unwanted operations and improving continuity of service to users.
