Power Quality Enhancement in Power System with Electric Arc Furnaces by Shunt Active Power Filter Optimum Design

In this paper the design of optimum shunt active power filter in order to improve the power quality indices in power systems with electric arc furnaces will be discussed. The selected model for the arc is based on a combination of Cassie-Mayer equations. The conventional controllers are not capable of improving the power quality for these types of systems. Therefore, for improving the power quality indices a new method based on fuzzy controller is employed to design an optimum shunt active power filter. The simulation results show the advantages of using fuzzy control.
