The behaviour of TSR-based SVC and TCR-based SVC installed in an infinite bus system

In this paper, effects of both Thyristor Switched Reactor-based Static VAr Compensator (TSR-based SVC) and Thyristor Controlled Reactor-based Static VAr Compensator (TCR-based SVC), which are two of shunt Flexible AC Transmission Systems (FACTS) devices, on load voltage in a single-machine infinite bus (SMIB) system are investigated. The modeling and simulation of TSR-based SVC and TCR-based SVC are verified using the Matlab7.04® SimPowerSystems Blockset. A six-pulse generator is used to control of TSR in the SVC. A fuzzy logic controller is used to control of TCR-based SVC. 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 TSR-based SVC and TCR-based SVC.
