摘　　要：为有效解决由于电力电子和非线性负载的应用引起的电网谐波问题,开展了混合有源电力滤波器(HAPF)谐波治理的研究。针对传统谐波检测方法存在的不足及有源电力滤波器(APF)存在相角延时等问题,提出了改进锁相环(PLL)的瞬时无功检测算法;在Matlab/Simulink中搭建基于改进PLL的瞬时无功检测法的HAPF仿真模型,并通过与传统PQ检测法仿真对比,验证了改进PLL的瞬时无功检测法的有效性;最后,为验证所提HAPF谐波治理的正确性以及实用性,在实验室搭建三相HAPF的样机进行相关硬件实验,实验结果验证了所提改进PLL的瞬时无功检测法的有效性。In order to solve the harmonic problems caused by the application of power electronics and nonlinear loads,the harmonic control of hybrid active power filter(HAPF)is studied.In view of the shortcomings of the traditional harmonic detection method and the phase angle delay of the active power filter(APF),the improved phase locked loop(PLL)instantaneous reactive power detection algorithm is proposed.The HAPF simulation model based on the improved PLL instantaneous reactive power detection method is built in Matlab/Simulink,and the improved PLL instantaneous reactive power detection method is verified by comparing with the traditional PQ detection method.Finally,in order to verify the correctness and practicability of the harmonic control of the proposed HAPF,a three-phase HAPF prototype is built in the laboratory to carry out relevant hardware experiments,and the experimental results verify the effectiveness of the improved instantaneous reactive power detection method of the PLL.
