摘要
This paper proposes a new control method for three-phase shunt active power filter (SAPF) by applying neural network inverse (NNI). The key of the proposed method is to decouple the SAPF system under the synchronous orthogonal d-q frame into two one-order linear subsystems, which concern the compensation current components. In addition, the linear closed-loop controllers are designed, respectively, for two compensation current components. Simulated results verify that by adopting the proposed method, the system has both good steady-state and dynamic performances. After the compensation, the total harmonic distortion (THD) of the power source currents in steady state is reduced from 25.57% to 1.23%.
