Simulation of (Matlab) Design and Analysis of TCSC Controller based on PSS of 210MW Synchronous Generator

Abstract

In our project we present the modeling, simulation and tuning of Thyristor Controlled Series Compensator (TCSC) controller for the improvement of power system stability for a 210 MW Synchronous Generator. Different controller structures namely Lead-Lag (LL) and a proportional-integral-derivative PID for TCSC controller have been proposed and a comprehensive assessment of the effects of the tuned TCSC controller on test power system have been carried out. The controller parameters have been tuned using particle swarm optimization for IAE performance index of the power system. It will improve both voltage stability and load angle stability. The proposed PSO based TCSC controllers damp out the oscillations in the state variables of the Single machine system.
