针对目前已有的有源电力滤波器控制策略的缺陷,本文提出了一种新型的非线性控制方法----基于电流跟踪的单周控制方法.在采用ip-iq法进行谐波检测的基础上,将这种控制策略用于并联混合型有源滤波器(SHAPF)进行谐波补偿,同时,利用PSCAD/EMTDC仿真软件,搭建了谐波源电路,并对并联混合有源滤波器的拓扑结构及其相应参数进行了设计.仿真结果表明,上述控制方法能使SHAPF有效工作,可以实时、准确地检测出各次谐波电流,并能有效抑制谐波,具有一定的可行性.

@@@@This paper proposes a new nonlinear control method--one-cycle control (OCC) based on current tracing is proposed to overcome the limit of the present control method of APF. Basing on detecting harmonic currents with the ip-iq method, the method of OCC based on current tracing is used to SHAPF in order to detect harmonic currents which make up for them in grids. At the same time, a SHAPF model based on PACAD/EMTDC is built and the related parameters are designed. The simulation result shows that the method can detect harmonic currents flexibly, accurately, but also supply reliable harmonic current component for harmonic restraint, therefore, it has certain feasibility.
