Design of series active filter for power quality improvement

The voltage quality is one of the major concerns for industrial and distribution consumers. In this work, a series active filter for voltage compensation has been verified using vectorial power theory for a three-phase system with non-linear load. The simulation has been designed using MATLAB/Simulink. The control scheme provides better unbalance voltage compensation and voltage regulation for three phase system with non-linear loads which operates in different conditions. The design and simulation of series active filter performance results were presented in this paper to show effectiveness of controller.
