Configuración óptima de alimentadores y estudio de coordinación de protecciones de la subestación Sambocity de CNEL EP

Abstract

The present work performs the load distribution and the study of coordination of protections of the Sambocity Substation, owned by the national electrical corporation CNEL EP, located in the Daule canton of the province of Guayas at kilometer 6 of Av. León Febres Lamb. After carrying out the electrical survey of the medium voltage networks and collecting the system data, we proceed to carry out the power flow analysis in current and future conditions, both in maximum and minimum demand, which will provide us with relevant information on the voltage levels in the busbars, consumption and chargeability of the elements of the system, additional is carried out the short circuit analysis in bar of 69kV and 13.8kV of the substation providing the three-phase fault currents, line-line, line-line-ground, line - ground , which will serve to performs the adjustments and coordination of protections of the substation, all this through the ETAP Software.
