摘　　要：采用了基于瞬时无功功率理论的ip-iq法来进行谐波检测,利用TMS320F2812芯片作为有源电力滤波器的处理器,对影响该算法的低通滤波器进行设计研究。实验结果表明,二阶Butterworth数字低通滤波器具有良好的低通特性,满足了谐波检测的精度和实时性。To adopt ip-iq method based on instantaneous reactive power theory carries out harmonics test, using TMS 320F2812 chip as the processor of active power filter, carries out design study for low pass filter which has impact on the calculation method. Experimental results show that Butterworth digital low pass filter has good low pass characteristics, which meets precision and real time of harmonics test.
