| 中文摘要: |
| 电流跟踪控制策略是决定并联型有源电力滤波器(active power filter,APF)补偿性能的关键。针对并联APF常规电流比例积分(proportional integral, PI)控制方法对负载主要次谐波分量补偿不充分的问题,提出一种适用于APF的新型指定次谐波电流控制策略。控制策略在常规电流PI控制基础上,对负载电流主要次谐波(5、7、11、13次)进行比例谐振(proportional resonant,PR)控制,而对其余次谐波采用常规PI控制。仿真结果证明了控制方法的有效性和正确性。 |
| 英文摘要: |
| Current tracking control strategy is the key to determine the compensation performance of parallel-connected active power filters (APF). With respect to insufficient compensation of the main sub-harmonic component of the load in the conventional parallel-connected current proportional-integral (PI) control, this paper presents a new selective sub-harmonic current control strategy suitable for APF. Based on the conventional current PI control, this strategy implements proportional resonant (PR) control over the main sub-harmonics of the load current (the 5th, 7th, 11th and 13th) and adopts conventional PI control over other sub-harmonics. Simulation results prove the correctness and effectiveness of the proposed control method. |
