Estudio de Polarización del Relé Direccional a Tierra ANSI 67N en las Líneas de Transmisión de 230 KV Pertenecientes a la Empresa de Energía de Bogotá

Abstract

This document contains the procedure carried out for the development of the study of polarization of ANSI 67N directional earth relay in 230kv transmission lines belonging to the energy company Bogotá, Which plays an important role in the transmission of electricity nationwide. This project was proposed as a way to provide a new alternative in the process of conducting studies protections. This is the project of internship as a form of degree according to the guidelines of the agreement 038 Universidad Distrital Francisco José de Caldas. It has been identified as coordination studies protections made today do not include the breakdown and detailed settings ANSI 67N leaving the typical values ​​that the installation of the relay is performed, which can bring different considerations and even more worrisome problems operation on lines with specific configurations, certain locations, connection between different types of node connection topologies, distance from them and own system imbalances that affect the behavior of the protections preventing comply with the characteristics of reliability and safety.
