摘　　要：角型级联式有源电力滤波器(APF)在中高压和大功率场合的谐波抑制上具有广泛的应用。首先建立了角型级联式APF的数学模型,提出了一种无谐波检测环节的系统控制策略,给出了控制策略中各个环节实现方法。在该控制策略中电流内环采用准比例谐振(PR)控制器,消除了传统APF的谐波检测环节,使得整个控制更加简洁,并同时实现了对谐波电流的无静差跟踪。仿真和实验结果证明了所提控制策略的有效性。The delta-connected cascade active power filter(APF)is widely used in harmonic suppression in medium and high voltage and high power applications.Firstly,the mathematical model of the delta-connected cascade APF is established,a system control strategy without harmonic detection is proposed,and the realization methods of each link in the control strategy are given.In this control strategy,a quasi proportional resonant(quasi-PR)controller is used in the current inner loop,which eliminates the harmonic detection of traditional APF,makes the whole control more concise,and realizes the non-static error tracking of harmonic current.Simulation and experimental results demonstrate the effectiveness of the proposed control strategy.
