Diseño eléctrico de la subestación El Bosque de 20/24 MVA a 69 KV con 4 circuitos de salida de 13,8 KV en la ciudad de Machala

Abstract

This project presents the design electrical of the substation El Bosque. The capacity of the substation is determined by the projection of the demand to long term of the electric system of the CNEL El Oro. Is established the characteristics of the substation equipment. Is effected the coordination of the protections of the phase overcurrent and ground tested with the program CYME International T&D. Is established the grid design grounded in compliance with IEEE Standard 80-2000. The design of lightning stroke protection is based on the Model EGM by rolling sphere method. It performed the calculate of the transformer power of the auxiliary services and it determined the ability of the bank and battery charger.
