Controlling Transmission Line Power Parameters By Using UPFC

FACTS devices expands the range of options aimed at controlling power delivery along with increasing capacity of current and new lines. The UPFC(unified power flow controller) is a highly complex power electronic interface that could regulate a voltage bus(local) along with optimize power flow in an electric drive system at the same time. By connecting the UPFC at the transmitting and receiving ends, this paper shows how to manage actual as well as reactive(VAR) power flow across the transmission channels. Main aim is to figure out how to monitor and perform a UPFC that will be installed at the transmission line to control complex power flow. Complex power via the transmission line cannot managed if no UPFC is mounted. To test the UPFC's results, simulations are run in the Matlab/Simulink setting.
