| 摘 要： | 针对谐振阻抗混合型有源电力滤波器的结构特点,建立了谐振阻抗混合型有源电力滤波器的数学模型。在该数学模型基础上,分析了基于检测电网侧谐波电流和负载侧谐波电流的复合控制策略下电流放大倍数变化、电网阻抗变化、无源滤波器失谐和基波串联谐振电路失谐对有源电力滤波器滤波特性的影响。仿真结果表明,该混合型有源电力滤波器具有良好的滤波特性,所得结果可为实际应用提供有效的参考。

| Abstract: | The resonant impedance hybrid mathematical model of active power filter(APF) was established based on the structure characteristics of APF.Based on the control strategy of detecting grid harmonic current and load harmonic current,the impacts of current output gain,electrical networks fluctuation,passive power filter detuning and fundamental series resonant circuit detuning were analyzed.The simulation results show that this hybrid APF has good filter characteristics,and the results can provide effective reference for practical application. |
