Improvement of Power System Transient Stability Using Static Synchronous Series Compensator
Chauhan Dharmendrasinh,  Mr. Ankit Gajjar
The power system industry is a field where there are constant changes occurs. Economic and environmental pressures force electric companies to enhance the power transfer capability of the existing transmission lines instead of constructing new ones. Besides allowing a better utilization of existing power systems capacity, FACTS controllers can control network parameters, such as magnitude of sending-end and receiving-end voltage, and active-reactive power, to improve both the transient stability performance of the system. In thesis work describe the Static synchronous series compensator device, that controls the power flow of the transmission line during sever disturbances. Basics of Static synchronous series compensator is that it does not contains bulky component like reactor and inductor so this device is more economical compare to conventional devices. And characteristic of Static synchronous series compensator is that injects or absorbs the reactance in the system and control the power. In thesis work two machine bus system with and without discrete PI controller and SSSC converter simulated in MATLAB .Simulation result obtained for selected Bus-3 in two machine power system shows that with SSSC the active-reactive powers, voltage - current compensation and damping out oscillation appropriately. In short in the power system when any disturbance occurs at that time if Static synchronous series compensator controller is connected at there so any disturbance occurs on the system may reach steady state condition very quick.
