The behavior of Thyristor Switched Capacitor (TSC) installed in an infinite bus system

Abstract

This paper examines the effects of thyristor switched capacitor (TSC) on load voltage in a single-machine infinite bus (SMIB) system. The modeling and simulation of TSC are verified using the Matlab/Simulink 7.04reg and SimPowerSystems blockset. The studied power system consists of a synchronous generator connected to an infinite bus and a static load. The results show that improvement on reactive power compensation and load bus voltage regulation could be achieved by using the TSC. Also, the test system with TSC is not needed a harmonic filter and low frequency voltage oscillations are damped by using TSC.
