PERFORMANCE ANALYSIS OF POWER OSCILLATION DAMPING USING SSSC FACTS DEVICE

D.V.N. Anantha, B. Vijaya Lakshmi

Fault in a system is inevitable, synchronous generator may become unstable so AVR and PSS are used to improve stability of synchronous generator and there by power system stability improves. The FACTS devices like SSSC used to damp power system oscillations and improve system performance apart from AVR and PSS with SSSC- rotor angle, EMT, electric power output oscillations- damped out quickly. In this work 2-area 4-generator system is considered and SSSC device is used as compensating device to stabilize the system. The effect of SSSC on fault currents and system stability in the circuit are studied and results proved efficacy of its behavior. The complete digital simulations are performed in the MATLAB/Simulink environment to provide comprehensive understanding of the issue.
