Power system stability is defined as the ability of power system to preserve it’s steady stability or recover the initial steady state after any deviation of the system’s operation. This paper investigates the effects of Static Var Compensator (SVC) on voltage stability of a power system. This paper will discuss and demonstrate how SVC has successfully been applied to power system for effectively regulating system voltage. Present time power systems are being operated nearer to their stability limits due to economic and environmental reasons. Maintaining a stable and secure operation of a powersystem is therefore a very important and challenging issue. Shunt FACTS devices play an important role in improving the transient stability, increasing transmission capacity and damping low frequency oscillations. In this paper shunt FACTS device-SVC is used in a two machine system for improving the power system stability. MATLAB software has been used in this study.
