摘　　要：并联电容器组是目前电网中普遍用来补偿无功的装置 ,而无源滤波器通常用来吸收谐波源产生的谐波电流 ,并兼顾无功补偿。文中以工程实例为依据 ,用电力系统谐波计算程序 CHP对补偿电容器组串联电抗对无源滤波器性能的影响进行了分析计算。结果表明 ,无源滤波器与补偿电容器组并联运行情况下 。At present the parallel capacitor banks are the widely used devices to compensate reactive power in power network, and to absorb the harmonic currents caused by harmonic sources the passive filters consisting of reactors and capacitors are applied and at the same time the reactive power compensation is performed. On the basis of paractical engineering example, The affection of compensating capacitor bank in series with reactor on passive filter is analyzed and calculated by CYME Harmonic Program (CHP) imported from Canada. Calculation result shows that when passive filter is operated in parallel with compensating capacitor bank in series with different reactor, both the frequency characteristics of the impedance of power supply system and the performance of filter will be affected.
