摘　　要：近年来谐波治理得到了各方面的重视。有源电力电子滤波器是当今治理谐波的主流。现阶段大部分有源电力电子滤波器的核心在于对电网侧电流的谐波检测。通过分析有源电力电子滤波器中交流侧与直流侧的能量交换,推导出了谐波检测的不必要性,最后引出了基于无谐波检测的有源电力电子滤波器,并讨论了与其相关的控制策略。同时在MATLAB上分别对基于无谐波检测的电力电子滤波器与基于谐波检测的电力电子滤波器分别进行了仿真。通过对二者结果的比较可以得出,基于无谐波检测的电力电子滤波器能够较好地抑制非线性负载产生的谐波,同时也分析了基于无谐波检测电力电子滤波器的优点与不足。Harmonic suppression has been one of the valued fields in recent years.Nowdays,power electronic filter is the main way to reduce the harmonic.Most of the power electronic filter is based on the detection of Harmonic current.This paper deduces that measuring harmonic is not necessary by introducing the energy exchange between DC side and AC side of power electronic filter.Therefore,we can come up with power electronic filter based on non-harmonic detection technology and discuss the control strategy of it.To verify the availability of the filter,power electronic filter is simulated in Matlab.The result of simulation indicates that power electronic filter based on non-harmonic detection technology can restrain harmonic.At the same time,comparing the result with the result of power electronic filter based on harmonic detection technology,we can get the advantages and disadvantages of the power electronic filter based on non-harmonic detection technology.
