Performance Enhancement of Shunt Active Power Filter using Soft Computing Techniques

Annu Govind, Vijay Kumar Tayal, Prakash Kumar


Paper present a shunt active power filter (SAPF) based compensation method for removal of current harmonics. The method includes a 3-phase supply system with a current controlled voltage source converter (CC-VSC) having input coupling inductor and output tank capacitor for self-supported DC bus. The performance of active power filter can be enhanced by using soft computing techniques such as artificial neural network (ANN) controller and gravitational search algorithm (GSA) for generating control signals of the SAPF. The current reference is calculated to compensate source current THD with synchronous reference frame (SRF) technique with proportional integrator (PI) controller. The proposed structure is simulated using MATLAB/Simulink and subsequently experimentally verified. The presentation of the system is originated to be suitable for numerous features of power quality enhancement structure.
