| 摘 要： | 针对瞬时无功理论的检测方法中Butterworth低通滤波器存在动、静态特性难以兼顾的弱点,选用Butterworth滤波器和均值滤波器串联的形式作为优化低通滤波器,通过均值滤波器抑制Butterworth滤波器的输出纹波,选用2阶Butterworth滤波器以加快检测速度.实验表明,该优化低通滤波器既可以保证畸变电流的检测精度,又具有较快的响应速度.

| Abstract: | For aberrance current detecing based on the instantaneous reactive power theory,it's difficult for Butterworth filter to acquire famous dynamic and static state characteristics at the same time.This paper proposed an optimized design using Butterworth filter and FIR filter in series,which utilized FIR filter to suppress the output ripple of 2 order Butterworth filter.Experimental results showed that this optimized filter can achieve both high precision and heart-stirring dynamic response simultaneously. |

| Keywords: | instantaneous reactive power harmonic and reactive detecting low-pass filter |
