Analysis of Homochronous Closing Circuit of Capacitor and Ferromagnetic Resonance of Transformer
摘要
Abstract
When the shunt capacitor banks carry out the reactive power compensation,the ferromagnetic resonance be-tween shunt capacitor banks and transformer core coil may come about due to the improper way of opening up and closing circuit breaker switch. Through the phenomenon of the system overvoltage when the circuit breaker switch clo-ses homochronously ,the volt-ampere characteristic of shunt capacitor bank and transformer core coil will be analyzed in this paper. The mechanism and characteristics of ferromagnetic resonance will be given out when the ferromagnetic resonance occurred,and the specific measures will be presented that it can effectively suppressed the occurrence of ferromagnetic resonance. Simulation results verify the theoretical analysis and correctness of the suppression method.关键词
