【 摘 要 】

Problem statement: The disturbance in power system is unavoidable situation. It causes inpower system oscillation. Approach: This study applied the Static Var Compensator (SVC) to damppower system oscillation. The stability criterion of the Lyapunov is applied to derive the controlstrategy of SVC. The simulation results are tested on a Single Machine Infinite bus. The proposedmethod is equipped in sample system with disturbance. The generator rotor angle curve of the systemwithout and with a SVC is plotted and compared for various cases. Results: It was found that thesystem without a SVC has high variation whereas that of the system with a SVC has much smallervariation. Conclusion: From the simulation results, the SVC can damp power system oscillaton.
