This paper proposes an intelligent control method for shunt active power filter to compensate the harmonic distortion in three phase power systems. For electric power systems, harmonics contamination generated by the nonlinear nature of the load is a serious and harmful problem. Shunt active filter (AF) has been employed to mitigate line current harmonics. In the presented system, Fuzzy Logic Controller (FLC) is first designed to implement the AF. Then the initial training data with two inputs, the error and derivate of the error, and one output signal from FLC can be obtained. Finally, a Neural Network (NN) with on-line training features is designed by using S-function in Simulink to achieve better performance. Simulation results show the effectiveness of the proposed active power filter system which improves the power quality, reduces the current harmonics and obtains better transient and steady-state responses.
