摘要
阐述有源补偿器控制系统的工作原理。基于交直流侧时瞬功率平衡原理,建立了d-q-o坐标系下直流侧电压闭环动态数学模型,推导了系统在比例积分控制下的稳定性判据,获得了主电路参数对系统稳定性影响的重要结论。通过对控制器有关参数的优化设计及仿真分析,证明了理论分析的正确性。
The operating theory of the control system for an active power filter (APF)is expounded.According to the instantaneous power balance equation between the AC and DC sides of an APF,the dynamic mathematical model of DC voltage control in d-q-o coordinates is derived.The stability criteria under proportional-integral (PI) control and some importand conclusions about the influence of parameters in main circuit on system stability are obtained.Optimal designs for some parameters of the controller and the digital simulation for system performance show that the theoretical analysis is valid.
