Estudios de cordinación de las protecciones por metodos computarizados

Abstract

This project presents in a very detailed way the study of adjustment and coordination when using Digital Relays to protect interconnection of barges such as Power Barge I and II with the SNI (National Interconnected System) at voltage levels of 69KV and 13,8KV, using characteristics of the protection elements’ curves along with Microsoft Excel 2007. In the making of this project several aspects have been taken into account, such as the study of electrical charge flow and the study of short-circuit on each bar. This allows us to obtain top results on charge flow and short-circuit to establish a reference at the moment of choosing the minimum adjustment of the protection devices, which will be previously chosen by a type and sensitive analysis of the kind of protection we wish to implement.
