【 摘 要 】

Problem statement: The disturbance in power system is unavoidable situation. It cause involtage sag in power system. Approach: This study applied the STATCOM to mitigate voltage of thesystem. The mathematical model of power system equipped with a STATCOM is systematicallyderived. The presented mathematical model is shown how it effects on voltage sag improvement. Thesimulation results are tested on a Single Machine Infinite bus. The proposed method is equipped insample system with severe disturbance. The variation voltage of the system without and with aSTATCOM is plotted and compared. Results: It was found that the system without a STATCOM hashigh voltage variation especially voltage sags whereas with a STATCOM the system voltage hassmall voltage sages. Conclusion: From the simulation results, the STATCOM can mitigate voltageof power system.
