摘要
Abstract
Dual closed-loop control method based on dq coordinate system is usually used for three-phase PWM rectifier. In this way,the dynamic performance of active current is restricted to the AC-side voltage of VSR. An existing method for improving dynamic performance is using the reactive current during the transient process. Based on deep research,pointed out the problems in existing improved method,adjusted the decoupling compensation,and presented a new control method,in which the steady-state value of AC voltage of VSR was used as compensation term of control value. The simulation results show that the proposed method can further optimize the dynamic performance and reduce its reliance on the regulator parameters.关键词
