Estudio de la coordinación de la protecciones por métodos computarizados aplicados a la subestación tecnova

Abstract

In any electrical system is vital to have a scheme that guarantees security and the perfectly functioning involved equipment. In this article we study the coordination of the protections of the electrical substation TECNOVA company considering future load growth in its facilities. The first step is performed load flow study which allows me to meet the system is full load current, these values are data necessary for the study of coordination. After getting the full load current, is a study of short circuit on the main points of the system considering as bars representing electrical equipment rooms, so that reveal the corresponding fault currents. After obtaining the necessary information is made coordination of the system protections considering the important points where they apply the criteria for the study. The analysis is performed using the Power World platform and Microsoft Excel as a support tool to perform calculations and graphs of the curves of the elements. Finally we got the SEL 587 settings, equipment used in the electrical substation for their respective protection.
