Analysis and Processing of Active Components in the Power Network Harmonic

引入电压畸变的p-q检测方法对电压、电流波形均有畸变的情况进行有效地检测基波电流与谐波电流的有功分量,进而获得需要补偿的基波无功电流和谐波非有功电流。应用该方法进行有源滤波,既能保证负荷所需的全部有功能量,同时也能降低滤波器本身的容量需求。

The paper considers that there are some inductive load which must be provided the active components in harmonic waveform by source and analyses the p-q method with distorted voltage, in which we can obtain the sum of reactive fundamental and harmonic currents easily. With the method, the active filter would compensate reactive power and reduce power loss at the same time.
