The objective of this paper is to determine the improvement in transient stability of IEEE 9Bus system using STATIC VAR compensator. SVC is one of the FACTS devices which can make the power supply more efficient and reliable. Power systems are continuously subjected to various types of disturbances which in turn cause the problem of losing stability. Transient stability is one of the most important stability of the power system. The loss of Transient stability is due to varies disturbances like faults, sudden change in loads and tripping off the lines after fault or heavy loss of loads. Power systems are Operating nearer to their stability limits due to economic and environment reasons. In under damped Power systems disturbances lead power system into unstable state. So, the tools for mitigating such a sensitive problem have an important significance. Static VAR Compensator (SVC) can control reactive power and therefore it is used to improve transient stability as well as the voltage profile. The proposed work includes IEEE 9-Bus Test system incorporated with SVC controller using Mipower Software. The simulation shows how the oscillations are damped out with SVC controller.
