摘要
电力系统中的非线性负载引发的电源污染得到人们越来越广泛的关注。针对这一问题对一种典型非线性负载电流的谐波用波形法和直流测量法进行了分析。对谐波畸变率对广义功率因数的影响进行了讨论,最后给出了几种降低谐波的方法。
In power system, power sources pollution caused by nonlinear load is taken people more and more attention. Regarding to the problem, we analyze a typical nonlinear load current harmonic wave through waveform method and DC measurement. The influence of distortion rate of harmonic wave on the power factor is discussed, and finally gives several methods to reduce the harmonic wave.
