Simulation and Performance Analysis of SSSC with Power Oscillation Damper Controller

In modern electric power system. The Massive use of the nonlinear and time varying devices has led to distortion of voltage and current waveforms. As a consequence, recently the issue of power quality has become important at both electric utility and end users of electric power. Power engineers consider rising power quality and giving certain power at the lowest cost in a major situation. This Achievable solutions to power distribution have been recommended by the use of, a number of power electronic based devices for enhanced power quality. Distribution Static Compensator (SSSC), Distribution Voltage Regulator (DVR), Unified Power Quality Compensator (UPQC), Battery Energy Storage System (BESS), HVDC Light are few of the prominent custom power devices employ at distribution level. This paper present the model of a static synchronous series compensator (SSSC) with an additional controller, power oscillation damper (POD) to reduce harmonic distortion and decrease clearing time of inter area oscillations to improve power quality. This paper proposed modeling and simulation has been analysis on MATLAB/Simulink software The simulation result show that, The power system oscillation are damped out rapidly with the use of power oscillation damper. The performance of the system is simulated for Linear and Motor load.
