Impact of PSS and SVC on the power system transient stability

The Power System Stabilizer (PSS) is a control device which ensures maximum power transfer and thus the stability of the power system enhancement. The PSS has been widely used to damp electromechanical oscillations occur in power systems and which are due to disturbance. If no adequate damping is available, the oscillations will increase leading to instability. The Static Var Compensator (SVC) is also used to improve stability in the system because of its role in reducing the reactive power in the electrical transmission lines. This paper presents an application of (SVC) in electrical transmission lines and PSS in two areas, two generator test power system. Using Matlab software to design and implements control system and study the effect of damping oscillations in stability power system after proposed faults in transmission lines of research model that used (PSS-generic and multiband) types and automatic voltage regulator (AVR).
