Modeling and Simulation of Unified Series Shunt Compensator for Power Quality Improvement

Power Quality in the distribution system is the important issue for industrial, commercial and residential applications. An increasing demond for high quality, reliable electrical power and an increasing number of distorting loads have led an increased awareness of power quality both by customer and utilities. This paper deals with the simulation of a Unified series shunt compensator, which is aimed at mitigating most of the Power Quality problems such as Voltage sag compensation, Voltage swell compensation, Voltage Flicker reduction, Voltage Unbalance mitigation, UPS mode operation. The modeling and simulation of the USSC has been carried out by using Facts controller. The USSC simulation model comprises of two 6 pulse inverters which are connected in series and in shunt to the system. The USSC is designed by using MATLAB SIMULINK based simulation for the working of the USSC. The USSC has mitigated several Power Quality problems giving better performance.
