摘要
无源滤波器广泛的应用于电力系统谐波治理工程中,其滤波效果与供电变压器的漏抗大小密切相关。先对无源滤波器的基本原理进行了分析,再根据其滤波等效电路分析了供电变压器的漏抗对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变压器的漏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。
A passive filter is widely used in harmonic treatment project of a power system,its effect is closely related to the size of transformer leakage reactence.First,the basic principle of the passsive filter is analyzed,then,according to its filtering equivalent circuit,analyze the effect of service transformer leakage reactance on the harmonic current flow of the filter.Finally,the experiment has been proven that the leakage that reactance is properly increased can improve filtering effect of the passivefilter.This conclusion has a great engineering guiding meaning.
