摘　　要：为有效改善长管道GIS互感器检定平台电源的电能质量,应用并联型APF补偿其中的谐波及无功,采用一种新型电流控制策略,直接检测网侧电流,电流控制环节采用PI控制器和谐振控制器分别作用于基波和谐波分量,用多个并联的谐振控制器根据补偿要求灵活设置谐波分量的补偿阶次,选择性补偿负载谐波,有效提高了并联型APF的补偿精度。最后,通过仿真及试验研究证明了该控制方法能有效降低谐波含量、提高电源的电能质量,具有重要的理论意义和使用价值。In order to effectively improve the power quality of the GIS transformer test platform,the shunt APF was used to compensate for the harmonics and reactive power.This paper proposed a new current control method which was based on the grid current detection.The PI controller and PR controllers in current control loop were respectively used to control the fundamental and harmonic components,and the multiple parallel PR controllers was used to set compensation order of harmonic components and the load harmonics according to the compensation requirements,which effectively improved the compensation accuracy of shunt APF.Finally,the simulation and experiment research verified the practicability of this control method.Therefore,it has important theoretical meaning and practical value.
