Coordinación de protecciones eléctricas para la Mini Central Hidroeléctrica Ing. Carlos Mora Carrión, de la Empresa Eléctrica Regional del Sur S. A.

Abstract

Ing. Carlos Mora Carrión Hydroelectric Plant is a bypass plant; it is in constant operation 365 days a year, with a plant factor over 90%, hence the importance of its protections. In the present work has the purpose of analyzing the settings of the electrical protections of the generators, therefore, a survey is made of the characteristics of the installed equipment, such as the primary equipment (generators, transformers, potential and current transformers, among others), and the digital relays that are installed in the Central. The analysis and procedure for the power flows and short circuits is made considering the standard IEEE Std C37.102 - 2006 focused on the theory, and the IEC 60909-0 standard on the software Power Factory for the simulation and analysis of short circuit events, flows and coordination curves, to define the feasible operating parameters of the generation units. Finally, the results obtained from the adjustment and calibration proposal of the plant protection system are presented, as well as the conclusions and recommendations that have emerged during the development of this work.
