SIMULATION AND EXPERIMENTAL MODEL OF UPFC USED FOR POWER QUALITY IMPROVEMENT OF TRANSMISSION LINE

Abstract

In this research, the significance of UPFC for improving the power quality of the transmission network will be discussed. UPFC is a dynamic and adaptable controller used in FACTS controllers that can regulate a number of transmission parameters, including series and shunt impedances, line voltages, current, active, and reactive power. The fundamental design of a UPFC consists of two voltage source converters, one of which is linked in parallel to the transmission line and the other in series. In this study, we will create Simulink and laboratory models of UPFC, and then compare their outcomes. Inverter and converter circuits were designed by using IGBTs.
