双环控制策略的并联有源电力滤波器研究

Study of Dual-loop Control Strategy for Shunt Active Power Filter

讨论了一种并联有源电力滤波控制器,建立了一种基于两相同步旋转的d,q坐标系控制方法。分析了主电路数学模型和双环控制策略,并在此基础上,将广泛使用的双闭环控制器工程化设计方法用于有源滤波器。实验结果证明了该控制方法对滤波器系统的正确性和有效性。

An Active Power Filter （APF） is presented in this paper.The control scheme is established in 2-phase synchronous rotating d,q frame （SRF）.The model of main circuit and dual-loop control strategy are analyzed.Based on the analysis,the engineering design technique of controller for dual-close-loop,which has been extensively used,is applied to the APF.Experimental results verify the feasibility and validity of the proposed control system.
