Voltage stability improvement and power oscillation damping using Static Synchronous Series Compensator (SSSC)

摘要

This paper investigates the problem of power flow control in a transmission line with the help of Static Synchronous Series Compensator (SSSC). Because of the enormous demand on power system has initiated the system to load heavily leading to voltage unbalance conditions. The static synchronous series compensator (SSSC) is capable of delivering a compensating voltage with an inductive and capacitive range. The complete simulation is done in the MATLAB/Simulink background. Simulation results confirm that the voltage and power oscillations can be damped well using Static Synchronous series Compensator (SSSC) with a PI controller under fault conditions. The transient mode is created by L-G fault. In order to tune the circuit and also to provide zero steady state error PI Controller is used here.
