Abstract

Power Quality (PQ) problem mostly refers to Voltage sag, ltage and source current problems and enhance power quality of the system. In this study the performance of new topology of UPQC namely open UPQC is investigated for the mitigation of balanced and unbalanced voltage sag, voltage swell and source current harmonics. The configurations of open UPQC namely Right Shunt Open UPQC (OUPQC-R) is analyzed with various control techniques .In this paper the capability of the OUPQC-R to enhance the power quality with reference generation and control techniques like Unit Vector Template (UVT) and Instantaneous p-q (PQ) is investigated. Various combinations of these techniques are also analyzed for the configuration of open UPQC. Simulation results carried out by using MATLAB simulink.
