Power system Stability Improvement using Static Synchronous Series Compensator (SSSC)

Geetanjali Babarao Raut, U. A. Jawadekar

Abstract


Day by day the demand of electric power system is increased and due to this continuous demand in electric power system network is becoming more complex and heavily loaded and leading to voltage instability. This paper presents the enhancement of voltage stability as well as damping power system oscillation in transient mode. In this study FACTS device (SSSC) static synchronous series compensator is used to investigate the effect of this device in controlling active and reactive power as well as damping power system oscillations. The SSSC is equipped with a source of energy in DC link, which can supply or absorb the active and reactive power to or from the line. PI controller is used to tune the circuit. For the simulation reason, the model of multi-machine power system with or without SSSC controller is established in MATLAB/SIMULINK using Sim Power System (SPS) block set.

 

Keywords: Static synchronous series compensator (SSSC), active and reactive power, proportional integral controller, two machine power system
