| 摘 要： | 目前电网的谐波污染越来越严重,有源电力滤波器由于能实时抑制谐波,所以得到外界广泛关注。谐波电流检测的好坏对有源电力滤波器的性能有很大的影响,所以,本文就目前的几种谐波检测方法:基于傅里叶变换、基于瞬时无功功率理论、基于同步参考坐标系原理、基于频域分析的模拟带通或者带阻、基于采样保持原理、基于Fryze时域分析、基于小波变换、基于Prony/Kalman估计、基于神经网络的谐波检测法/自适应滤波理论谐波检测法进行了概括和比较分析。

| Abstract: | The current harmonic pollution is increasingly serious and active power filter get the outside world wide concern due to its real-time harmonic suppression.The quality of harmonic current detection has a great influence on the active power filter.In this article,the present several kinds of harmonic detection methods based on Fourier transformation,transient reactive power theory,synchronous reference coordinate system theory,frequency domain analysis based on analog bandpass or bandstop,the sample and holding principle,Fryze time domain analysis,wavelet transformation,Prony/Kalman estimation,neural networks/adaptive filtering theory are summarized,compared and analyzed. |
