Abstract: Fast progression in field of power electronics has already started influence of the power industry. So Flexible AC transmission system (FACTS) devices provide fast control of active and reactive power through a transmission Line. In this paper transient stability will improving by using UPFC. The Unified power flow controller is a member of FACTS family with very attractive features. This is the combination of the properties of STATIC Synchronous compensator (STAT com) and Static synchronous series compensator (SSSC). Here we have been developed two simulation model of single machine infinite bus (SMIB) system i.e. With or without UPFC. These simulation has been incorporated into MATLAB based Power system Toolbox (PST) for their transient stability analysis. This models has been analysed for transient fault at different locations, i.e. At the middle and receiving end of the transmission line keeping the location of UPFC fixed at the receiving end of the line. Transient stability has been analysed with the help of curves of voltage magnitude during fault.
Keywords: UPFC, Transient Stability, MATLAB Simulation.
