【 摘 要 】

Abstract: Problem statement: Static Synchronous Compensator (STATCOM) and StaticSynchronous Series Compensator (SSSC) have been individually applied to improve stability of powersystem. Approach: This study presents the coordination of a STATCOM and SSSC for improvingpower system stability. The swing curves of the three phase faulted power system with various casesare tested and compared. Results: The swing curve of system without FACTS devices has undampedoscillation. The system with a STATCOM or a SSSC can increase damping of power system whereasthe system with coordination of a STATCOM and a SSSC provides the best results of stabilityimprovement Conclusion: From the simulation results, the stability of power system can be muchbetter improved by coordination control of a STATCOM and a SSSC.
