2、PENSATION：电力有源电力滤波器补偿,In this Presentation, a new Active Power Filter (APF) control scheme has proposed to improve the performance of the APF. This presentation presents a new technique with instantaneous power theory (P-Q theory) in order to control of APF under non- ideal mains voltage conditions.
3、 Performance of the proposed scheme has been found feasible and excellent to that of the instantaneous reactive power algorithms under various non-ideal mains test scenarios. MATLAB/SIMULINK power system toolbox is used to simulate the proposed system. The proposed methods performance is compared wi
