【 摘 要 】

Problem statement: Thyristor Controlled Series Capacitor (TCSC) and Static VarCompensator (SVC) have been individually applied to improve stability of power system.Approach: This study presents the coordination of a TCSC and SVC for improving power systemstability. The swing curves of the three phase faulted power system with various cases are tested andcompared. Results: The swing curve of system without FACTS devices has undamped oscillation.The system with a TCSC or a SVC can increase damping of power system whereas the system withcoordination of a TCSC and a SVC provides the best results of stability improvementConclusion: From the simulation results, the stability of power system can be much better improvedby coordination control of a TCSC and a SVC.
