Impacto de Banco de Capacitores en Alto Voltaje Sobre Interruptores de Propósito General, Aplicado a la Subestación Santa Rosa

Abstract

In this work analyzes the effects of the capacitive expansion in Santa Rosa substation of the National Transmision Sistem, provides a theoretical development and simulations and mitigation techniques in presence of closing capacitor circuit breaker and single-phase and three-phase faults occurring near to the substation. Mitigation techniques permit to take care of high current with high frecuency whose presence is a result of the expansion of capacitor banks. As regards to capacitor switching transients is found that the best technique for mitigating is the synchronized control of closing capacitor circuit breaker. While the best way to mitigate the frequency and outrush current of the capacitor banks during a fault either near to the autotransformer or in transmission line within the vicinity of the substation is the use of limiting inductances.
