摘　　要：运行中的电力电容器组一旦出现不平衡电流超标,就需要对电容器的组合方式进行调整。笔者通过理论计算及不平衡电流模拟测试,对1组桥差保护电力电容器组故障后调整实例进行了分析。结果显示,不平衡电流模拟测试法是对电容器进行调整后一种非常有效的检验方法。When the unbalanced current of the operating power capacitor bank exceed the standard,it is necessary to adjust the combination of capacitors. In this paper,an adjustment case after a group of H type protection power capacitor bank failure is analyzed by theoretical calculation and unbalanced current simulation test. The results show that the unbalanced current simulation test is a very effective testing method for capacitors adjustment.
