摘要
介绍了有源滤波器的基本工作原理，提出了1种新颖的基于小波变换的谐波和基波无功电流的检测方法．与傅里叶变换法仿真结果对比可知，小波变换是1种实时检测谐波及无功电流的更有效的方法。
The principle of active power filter (APF) is introduced, and then a new method for reactive currents and harmonics detection based on wavelet transform is proposed. Compared with the Fourier transform method, this method is more effective to real-time detecting the reactive currents and harmonics.
