针对某变电站10 kV馈线经常发生跳闸的情况，通过分析，认为其跳闸的原因是由于无功补偿装置中并联电容器组的串联电抗器参数设置不合理，在电网中的非线性负荷产生的谐波作用下，引起了并联电容器组的高次谐波电流放大而导致断路器跳闸，根据实际情况提出了解决的方案。

A deliberated study finds that the cause for feeder frequent tripping in a 10kV substation is the unreasonable parameter settings of series reactors in shunt capacitor banks of reactive power compensation device. Thus high harmonic currents in shunt capacitors are amplified by the effect of non-linear loads power system which results in the break tripping. The paper further proposes practical resolutions to the problems.
