Power System Stability Enhancement Using UPFC

Abstract

Abstract

The UPFC consist of two voltage-source converters, one connected to the power system through a shunt transformer, whereas the other is inserted into the transmission line through a series transformer. These two voltage-source converters are coupled through a common dc capacitor link. From the control perspective, the UPFC can be decoupled into two branches; the parallel branch formed by the shunt transformer, voltage source converter and dc capacitor operating as a STATCOM.

Keywords: UPFC, shunt transformer, series transformer, voltage-source converter, power system, STATCOM
