It causes in power system oscillation. Approach: This study applied the Static Var Compensator (SVC) to damp power system oscillation. The stability criterion of the Lyapunov is applied to derive the control strategy of SVC. The simulation results are tested on a Single Machine Infinite bus. The proposed method is equipped in sample system with disturbance. The generator rotor angle curve of the system without and with a SVC is plotted and compared for various cases. Results: It was found that the system without a SVC has high variation whereas that of the system with a SVC has much smaller variation. Conclusion: From the simulation results, the SVC can damp power system oscillaton.}, journal = {American Journal of Applied Sciences}, publisher = {Science Publications} }
