基于自适应逆控制的并联型有源电力滤波器的仿真研究

首次将自适应逆控制应用于并联型有源电力滤波器的控制,提出了一种新的并联型电力有源滤波器的控制方法.此方法把有源滤波器及主电路部分看作广义有源滤波器并利用其逆模型作为控制器对其进行控制.此控制算法对电路中的参数变化不敏感,不但简单易行,而且比较可靠有效,对理想三相电源电压能够产生较好的补偿效果,当电源电压出现畸变和不平衡时,仍能得到较好的补偿效果.仿真结果证实了所提出算法的可行性.

Simulation Research of the Shunt Active Power Filter Based on Adaptive Inverse Control

The algorithm of the adaptive inverse control is first used in the control of the shunt active power filter, a novel control algorithm of the shunt active power filter is proposed. The active filter and the main circuit are look as the generalized active filter and the inverse of its model is used as the controller to control the active filter. It has the advantage that its performance is senseless to the change of the other parameters of the circuit. This algorithm is reliable and easy to be implemented. It not only has good performance under ideal supply voltage, but works well when the supply voltage is distorted or unbalanced. Simulation results verified the feasibility of the proposed algorithm.
