Power system damping through coordinated design of power system stabilizer (pss) & different types of FACTS devices (SVC, SSSC & UPPC) is presented in this paper. In the condition of single phase fault power system stabilizer is enough to damp the oscillations for the two area system but the settling time increases for the whole system parameter, but in the case of three phase faults the whole system parameter goes into unbalanced condition and the machine losses its synchronism even in the presence of power system stabilizer, in that case PSS is not enough to suppress the faults, so the other compensator must put into action for the better stability of the two area system. PSS including with FACTS devices reduce the settling time and enhance the response time of the system for single phase faults and damp the oscillation for three phase fault and make the system stable. This paper contains coordinated simulink model of PSS & different types of FACTS devices for two area systems & checked for single phase fault and three phase fault condition with & without FACTS devices.
