Active Power Filter Control Strategy Without Phase-locked Loop Under Weak Grid Condition
摘要
Abstract
The impedance is large and the point of common coupling voltage usually occurs distortion,unbalance and offset for weak grid with high proportion of distributed energy resources connected with active power filte(r APF). For APF conventional control strategy,the phase-locked loop(PLL)has error under voltage distortion and imbalance condition,and improved PLL is usually complexity and introduces additional delay. An improved control strategy was carried out based on virtual coordinate. The control algorithm was simple and no need PLL. The simulation and experiment results show the improved control strategy ensures APF owns good accuracy and dynamic performance under weak grid PCC voltage distortion,unbalance and offset condition.关键词
