Simulation of Multi Converter Unified Power Quality Conditioner for Two Feeder Distribution System

In this Project the Power Quality improvement is done for elimination of Sag, Swell and Harmonics for two feeder distribution system by using Multi Converter UPQC. In this system two series voltage source converters and one shunt voltage source converter exits. The system can be applied to adjacent feeder to compensate for supply voltage and load current imperfections on the main feeder and full compensation of supply voltage imperfections on the other feeder. In this configuration all converters are connected back to back on the dc side and share common dc-link capacitor. Hence, Power can be transferred from one feeder to adjacent feeder to compensate Sag, Swell and Interruption. The performance of two feeder distribution system is studied using MATLAB/ SIMULINK.
