| 摘 要： | 为了抑制三相并联有源电力滤波器(APF)运行过程中参数变化对补偿效果的影响,提出了基于递推最小二乘算法的参数实时在线辨识控制策略。三相并联有源电力滤波器的参考电流则依据瞬时无功功率理论检测获得。该控制策略基于在线辨识参数将参考电流转换为相应的参考电压,通过空间矢量脉宽调制技术控制电压源逆变器的输出,使它产生对应补偿电流。该控制策略原理简单,能改善补偿效果并易于实际应用。仿真实验验证了该控制策略的可行性、可靠性及鲁棒性。

| Abstract: | An online parameter identification control strategy based on the recursive least squares method was developed to suppress the influence of the compensated effectiveness generated by parametric variations in three phase shunt active power filters(APF).The reference current obtained using instantaneous reactive power theory is transformed to a reference voltage based on the estimated parameters.With this reference voltage,the voltage source inverter generates the corresponding compensated current using space ... |
