摘　　要：研究并联电容器组运行中由于部分电容器故障退出后的谐波响应。综合电容器的有关谐波过负荷能力规定和一些研究成果,推荐电容器的谐波过负荷校验条件;分析由于电容器组缺台引起谐波分布的变化,对电容器组允许的缺台数量进行分析。The paper studies on the harmonic response of shunt capacitor bank running with some units turn off for fault. It recommends the harmonic permissible overcurrent and overvoltage for verifying the overload of capacitor after suming up the related prescription and some study results about harmonic overload capability of capacitor. Then it analyses the change of harmonic current flow as result of the capacitor bank runing short of some units. It analyses the permissible amounts of the shorting units.
