By adding an equivalent harmonic impedance in the branch circuit of power grid, this HAPF could force all the harmonic currents flow into passive power filters, which resulting in eliminating harmonic contamination more effective. And using the capacitive feature of PPF in the fundamental frequency, this HAPF could compensate fixed-capacity reactive power without increasing APF's burden. Moreover, in order to decrease APF's cost, the fundamental voltage will largely be endured by capacitor in view of the series resonance circuit tuned at the fundamental frequency, so the APF just bears little harmonic voltages.

其基本工作原理是：有源部分等效于在電網(wǎng)支路中串聯(lián)了一個(gè)諧波阻抗欧美性视频在线，該諧波阻抗對(duì)基波電流不起作用www.韩日欧黄色片网站.com，而對(duì)諧波電流產(chǎn)生很大阻礙作用国产亚洲AⅤ人片在线观看，迫使諧波電流流入無源濾波器，從而達(dá)到濾除諧波的目的国产av专区；同時(shí)新型注入式混合有源濾波器還充分利用了無源濾波器的無功補(bǔ)償功能偷拍偷窥一区二区综合，在不增加有源部分容量的前提下，可以提供一定容量的無功功率国产激情图区；由于有源部分承受的電網(wǎng)基波電壓不大免费人成视频在饯观看网站，也沒有基波電流流入，因此逆變器容量小日韩欧美精品视频在线观看，初期投資較小国产a第⑩页无毒。
