Comparison of FACTS devices for transient stability enhancement of multi machine power system

In this paper an examination has been performed for the upgradation of transient stability limit in two area multimachine power system using different FACTS devices. The simulation of two area multimachine power system including FACTS devices has been carried out in the MATLAB Simulink domain. The performance of unified power flow controller (UPFC) for the upgradation of transient stability limit has been investigated along with other FACTS devices such as static synchronous compensator (STATCOM) and static synchronous series compensator (SSSC) respectively. The paper establishes the superiority of UPFC over STATCOM & SSSC.
