Abstract-This paper will discuss and demonstrate how Static Var Compensator (SVC) has successfully been applied to control transmission systems dynamic performance for system disturbance and effectively regulate system voltage. SVC is basically a shunt connected static var generator whose output is adjusted to exchange capacitive or inductive current so as to maintain or control specific power variable; tyipically, the control variable is the SVC bus voltage. One of the major reason for installing a SVC is to improve dynamic voltage control and thus increase system loadability There are the mainly accomplishes work to construct an effective for SVC. Firstly, to design a controller for SVC devices on transmission lines, a Single Machine Infinite Bus (SMIB) system is modeled. A statedspace mathematical model is constructed which considers both electromechanical oscillations and reactive current of the SVC at the installation site. The installation site for this paper is Hlawkar generation station in Myanmar. And datas will also be taken from this station. Simulation results will be provided by using MATLAB programming. The SVC is more effectively enhance the transient stability and increase transmission capacity
