摘　　要：在对并联型APF交、直流侧能量传递过程分析的基础上,对APF常规控制进行了等效的演化研究,发现负载有功电流的检测环节的存在有害无益。根据有源电力滤波器谐波检测环节存在的不必要性论证,分别构建了有源电力滤波器在abc三相坐标系下的无谐波检测环节控制系统及三电平有源电力滤波器在dq坐标系下无谐波检测环节前馈解耦控制系统。最后,对三电平无谐波检测环节控制系统进行了仿真实验研究,仿真结果验证了无谐波检测环节补偿的可行性及有效性。Based on the analysis of the energy transfer process on de, ac side type shunt APF, the equivalent of APF control the evolution of the＇ study, found that the load of active current detection link is more harm than good. According to active power filter harmonic detection link is not the necessity, build the active power filter in three-phase coordinate system respectively under harmonic detection link control system and three level of active power filter in the coordinates of harmonic detection link feed forward decoupfing control system. Finally, the three level without harmonic detection link simulation experiment research was conducted on the control system, the simulation results verify the feasibility and effectiveness of the harmonic detection link compensator.
