Damping Out Power System Oscillations for LLL - Fault in Multi-Area Power System Using Static Synchronous Series Compensator (SSSC)

A. Praveena

Abstract: The main aim of this paper is to damp out power system oscillations, which has been recognized as one of the major concerns in power system operation. In a Static Synchronous Series Compensator (SSSC), a controllable AC voltage is generated by a voltage-source converter. There are two control channels for controlling the magnitude and phase of the voltage. This paper describes the damping of power oscillations by static synchronous series compensator (SSSC) based damping controllers. The advantage of this approach is that it can handle the nonlinearities, at the same time it is faster than other conventional controllers and it improve the reactive power of the system. Simulation studies are carried out in Matlab/Simulink environment to evaluate the effectiveness of the proposed Static synchronous series compensator (SSSC) of multi-area power system. Results show that the proposed SSSC based damping controllers improve the damping performance of the in the event of a major disturbance
