摘　　要：针对电网中的非线性及无功负载问题,采用了H∞重复控制下的并联逆变器电能质量治理方法。H∞重复控制设计简单,能够抑制逆变器谐波,且参数小范围波动时有着较好的鲁棒性;同时嵌入电能质量治理功能的逆变器,在并网发电时也能治理电能质量问题;最后在Simulink进行仿真实验,分析所提方法下并联逆变器治理前后波形,验证所提方法对非线性及无功负载的治理效果。A parallel inverter power quality control method under H∞repetitive control is adopted to address the nonlinearity and reactive loads in the power grid.The H∞repetitive control design is simple,can suppress inverter harmonics,and has good robustness when the parameters fluctuate in a small range.Inverters embedded with power quality control functions can also address power quality issues in grid connected power generation.Finally,simulation experiments were conducted in Simulink to analyze the waveform before and after the parallel inverter governance under the proposed method,and to verify the governance effect of the proposed method on nonlinear and reactive loads.
