查询词典 capacitive circuit

By means of forced synchronization of current in thyristor branch with the line current, the mode switching from capacitive mode to Bypass can be implemented. In the switching strategy from capacitive mode to inductive veriner mode, a method of thyristor conditional firing is put forward. The thyristors will be fired and conducted on condition that both line current and capacitor voltage are inphase.

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：有源部分等效于在电网支路中串联了一个谐波阻抗，该谐波阻抗对基波电流不起作用，而对谐波电流产生很大阻碍作用，迫使谐波电流流入无源滤波器，从而达到滤除谐波的目的；同时新型注入式混合有源滤波器还充分利用了无源滤波器的无功补偿功能，在不增加有源部分容量的前提下，可以提供一定容量的无功功率；由于有源部分承受的电网基波电压不大，也没有基波电流流入，因此逆变器容量小，初期投资较小。
