摘要
三相四线制有源电力滤波器(APF)在电网谐波的治理过程中,补偿效果会受到不平衡或畸变电压的影响。针对此问题,本文研究了一种改进的三相四线制APF控制算法,系统补偿非线性不平衡负载引入的谐波、无功及三相不平衡电流,并通过MATLAB验证其有效性。
Unbalanced and distorted supply voltage affects the compensation effect during the process when three-phase four-wire system active power filter （ APF） corrects power harmonic. Aiming at this problem, this article studies a control algorithm of an improved three-phase four-wire system APF in which harmonic, reactive and three-phase unbalanced current is introduced to the nonlinear unbalanced load of system compensation. The effectiveness of the algorithm is verified by MATLAB.
