摘要
谐波对电网和其他系统的危害越来越大。解决谐波问题的一种有效方法就是使用滤波装置,无源滤波器因其功率大、成本低等优势在大功率用电系统中得到了广泛的应用;有源电力滤波器(APF)由于有很好的滤波特性及动态特性好等优势一直得到广泛关注,但其容量又限制了其实际应用。将有源电力滤波器与无源电力滤波器相结合,构成混合有源滤波器(AF),取两者之长补有源电力滤波器之短,可以降低谐波补偿系统的成本,达到APF实用的目的。
Harmonic current endangers the electrical system and other systems. A good method of dealing with harmonic current is using the filter device. Passive power device is used widely because of its high power and low cost. Active power filter used for dynamic harmonic suppressing and compensation or reactive current can effectively improve power network quality. It is not used widely in the actual application because of its capacity. The adoption of hybrid active power filter can solve the problem
