摘    要:运行中并联电容器装置事故时有发生,由于电容器事故不作为考核事故统计,忽略了对电容器装置事故的分析。而设计人员在设计中也从来没有认真对变电站的谐波进行过详细的计算,谐波超标或放大时便造成了电容器的损坏。

关 键 词:并联电容器  谐波  并联谐振  解决方案

Abstract:Shunt capacitor installation accidents often happen in operation, capacitor accident are not counted as assessment accident, so the analysis on capacitor device accident is neglected. The designers have never minutely calculated for substation harmonic in design, when harmonic excess or enlarge can causes the capacitor damage.
Keywords:Shunt capacitor  Harmonic  parallel resonance  solutions
