Abstract

This paper presents the results for the performance of passive and active power filter to reduce harmonics in the distribution system. The harmonics analysis is performed in order to observe the percentage reduction of amplitude current harmonics and total harmonic distortion for passive and active power filter at various loads. In addition to that the bidirectional switching is used as a strategy control in active power filter. Representative result of circuit simulations is carried out. The results show that the active power filter can simultaneously attenuate various frequencies and are compared with passive filter which is only filtering an individual harmonics. Also, the significant percentage of reduction for the amplitude current harmonics and total harmonic distortion by active power filter are compared to passive filter. Furthermore, the sinusoidal current waveform quality at distribution lines which filtered by active power filter is better compared with passive filter. Therefore, the active power filter is good to reduce harmonics in the electrical distribution systems.

无源滤波器和有源滤波器在配电系统中的降谐波性能

本文介绍了无源滤波器和有源滤波器在配电系统中降低谐波的性能结果。为了观察无源和有源电力滤波器在不同负载下的幅值电流谐波和总谐波失真的减少百分比，进行了谐波分析。此外，在有源电力滤波器中还采用双向开关作为策略控制。给出了具有代表性的电路仿真结果。结果表明，有源滤波器可以同时衰减各种频率，并与只滤波单个谐波的无源滤波器进行了比较。此外，与无源滤波器相比，有源滤波器对幅值电流谐波和总谐波失真的降低率显著。此外，与无源滤波器相比，经有源滤波器滤波后的配电线路正弦电流波形质量更好。因此，有源电力滤波器对降低配电系统的谐波有很好的作用。
