为了避免有源电力滤波器（Active Power Filter,APF）输出电流控制算法中传统PI控制策略稳态误差较大的缺点,提出了新的分频控制策略。详细分析了分频控制策略的原理与实现方法,并建立Matlab仿真模型,对比分析了两种控制策略的控制效果,最后通过现场实验验证了分频控制策略的优异控制效果。仿真与现场实验结果均表明,分频控制策略能够提高APF输出电流的控制精度并提高谐波电流滤除率。

As traditional PI control strategy of output current control algorithm for active power filter（APF） has larger steady-state error,this paper proposes a novel frequency dividing control strategy.Detailed analysis of principles and implementation methods of the frequency dividing control strategy are given.Matlab simulation model is then established to analyze the effects of the two control strategies.Finally,an actual experiment is made to prove the excellent performance of the strategy.Simulation and actual experiment results show that the frequency dividing control strategy can improve the current control accuracy and compensation effect of APF.
