Power system has made a stunning entrance to the market.. The structured power systems has effected by different kinds of problems. Whether system stability problems or Power Quality issues, these issues need solving. Classically passive filters were used but nowadays active filters such as Static Var Compensator (SVC) has been chosen for the task. SVC is a device that regulates the voltage level or the reactive power in the system. It is used to maintain voltage stability, enlargement of critical clearing time. In this paper Simulation has been done with one example.
