UPFC is a combination of a Static Synchronous Compensator (STATCOM) and a Static Synchronous Series
Compensator (SSSC) coupled via a common DC voltage link. UPFC is a FACTS controller which can independently
control both real and reactive power through line. Transient stability of power system can be improved by placing
UPFC. In this paper transient stability enhancement of 11 bus system is done with help of UPFC. Time domain
simulation is carried out in PSAT (Power System Analysis Tool-box) in MATLAB by creating fault at a bus and results
show that UPFC increases the transient performance under large disturbance conditions by damping out the power
oscillations with less settling time.
