摘　　要：研究了谐振阻抗混合型有源电力滤波器RITHAPF(Resonant Impedance Type Hybrid Active Power Filter)的结构与工作原理,建立了该滤波系统的电气模型和控制方程。在此基础上,进一步分析了在基于负载谐波电流来控制逆变器输出电压的控制策略下,电网阻抗波动、无源滤波器失谐、基波串联谐振电路的失谐和参数的变换对滤波系统控制性能的影响。并给出了各种影响的仿真图,所得的结论可为RITHAPF在复杂工程的实际应用提供有效的指导。The topology structure and operating principle of resonant impedance type hybrid active power filter （RITHAPF） are studied, electrical modeling and control model equation of RITHAPF are established. Based on the control strategy of load harmonic current controlling inverter output voltage, the impacts of electrical networks fluctuation, passive power filter deruning, fundamental series resonance circuit deruning and system parameter changes on the control characteristics of RITHAPF are analyzed, and simulation graphs of different influences are given.The conclusion is a guidance on the safe and effective application of RITHAPF in complex projects.
