Abstract
with the growing power demand, it is vital to expand power transfer capacity of transmission lines. But the new expansion in our present transmission system is confined due to financial problems, environmental concerns and health hazards due to electric and magnetic fields. May be its worthwhile option to use flexible AC transmission system (FACTS) for enhancement of power capacity of transmission system. This paper presents, fruitfulness FACTS devices SSSC and TCSC with POD (Power oscillation damper) as additional controller. The major function is to decrease the peaks overshooting and clearing time of inter area oscillations, hence betterment in transient stability. For the fulfillment of analysis, time domain simulation outcomes are correlated for results verification. In addition, the parallel operation of SSSC for the system has been analyzed. This paper proposes modeling and simulation on MATLAB/Simulink Software for the proposed test system. Result displays that, power oscillation are rapidly damped than traditionally PSS by employing POD with FACTSControllers.
