An Improvement of transient stability performance with the help of Static Synchronous Series Compensator (SSSC) controller has been presented in this paper. The SSSC is used to control active and reactive powers as well as damping power system oscillations in transient mode. The results obtained from simulations validate the effectiveness of proposed modeling and tuning approach for power system stability improvement. The simulation results also show that the proposed SSSC controller is effective in the asymmetrical disturbance conditions in the power system. The obtained results justify that the proposed SSSC controller is found to be robust for fault location and change in operating conditions. For the simulation purpose, the model of three-machine power system with SSSC controller has been developed in MATLAB/SIMULINK using Sim Power System (SPS) block set.
