摘　　要：针对工业园区高比例电力电子负荷接入带来的电能质量问题,提出一种基于APF的带自适应谐波补偿限流功能的谐波阻抗控制策略。谐波阻抗控制策略可以对系统的指令电流进行无差控制并对各谐波分量进行独立控制,自适应谐波补偿限流可以有针对性地进行谐波补偿,两者相结合后可以对选取的各谐波分量进行单独控制,使限流后的谐波补偿效果明显提高。该控制策略在系统容量不超限时在Matlab/Simulink中搭建仿真模型,结果表明,该控制策略响应速度快,治理后的谐波总畸变率为2.91%,减少了27.08%,三相不平衡度为8.52%,减少了16.15%,补偿效果明显。Aiming at the power quality problems brought about by the high proportion of power electronic load access in industrial parks,a harmonic impedance control strategy based on APF with adaptive harmonic compensation current limiting function is proposed.The harmonic impedance control strategy can control the command current of the system without difference and control each harmonic component independently,and the adaptive harmonic compensation current limiting can target harmonic compensation,and the combination of the two can control each selected harmonic component individually,so that the effect of harmonic compensation after current limiting is significantly improved.The control strategy in the system capacity does not exceed the limit in Matlab/Simulink to build a simulation model,the results show that the control strategy response speed is fast,after the treatment of the total harmonic distortion rate of 2.91%,a reduction of 27.08%,three-phase imbalance degree of 8.52%,a reduction of 16.15%,the compensation effect is obvious.
