并联型有源电力滤波器的复合电流控制方法
Compound Current Control Method for Shunt Active Power Filters
摘要
Abstract
Aiming at the influence of nonlinear load on the quality of power grid,a shunt active power filter (SAPF)topology was researched. According to this topology,the mathematical model of the SAPF was established in the three-phase static coordinate system and the two-phase d-q synchronous rotating coordinate system. The transfer function of the model was deduced,and the current controller based on PI control was designed. By analyzing the limitation of PI controllers in current tracking control for active power filters,a compound control strategy combining repetitive control with PI control was proposed to improve steady state performance of the system. Experimental results demonstrate that the current control method combining PI control method with repetitive control method has a high steady-state compensation accuracy. It is able to effectively suppress harmonic currents caused by nonlinear loads and greatly improve grid current waveform.关键词
