| 摘 要： | 有源电力滤波器(APF)是一种动态抑制谐波的装置,其谐波电流检测环节直接影响到APF的性能。针对我国电网谐波污染较严重的现象,对基于瞬时无功功率理论的p-q和ip-iq两种电流检测方法进行分析。并对这两种检测方法分别建立了SIMULINK仿真模型,通过对这两种方法进行理论和仿真结果的对比分析得出p-q法只能用在对称且无畸变的APF中,ip-iq在三相电压不对称时会出现误差,所以其只能应用在三相电压是对称的APF中。

| Abstract: | The active power filter （APF） is a kind of dynamic device to restrain the harmonics. The harmonic current detection directly affects the performance of the APF. Aiming at the phenomenon that power grid harmonic pollution is relatively serious in China, this article analyzes the p-q and ip-iq electric current detection method based on instantaneous reactive power theory. And SIMULINK simulation model is established for the two detection methods. Through the study of the theory of the two methods and the comparison of simulation results, it is concluded that p-q method can only be used in the symmetric APF without distortion, and ip-iq error occurs in three-phase voltage asymmetry, so it can only be used in the APF with symmetric three-phase voltage. |
