摘　　要：无源滤波器广泛地应用于电力系统谐波治理工程中,其滤波效果与电力系统的运行方式密切相关。对无源滤波器的基本原理进行了分析,根据其滤波等效电路分析了电力系统等效阻抗对无源滤波器的谐波电流的流量影响,最后通过实验验证了适当的增大系统的等效阻抗可以明显的改善无源滤波器的滤波效果,此结论有很大的工程指导意义。Passive filters are widely used in harmonic improving project of power system. Its filter effect is closely relat- ed to the operating method of the power system. The basal principle of the passive filter is analyzed. Acoording to the fil- tering equivalent circuit, analyze the effect of the equivalent impedance of the power system on the harmonic current flow of the passive filter. Finally, the experiment has proved that it can distinectly improve the filtering effect of the passive fil- ter by proper increasing equivalent impedance of the system. The conclusion is of great guiding function.
