Abstract
Problem statement: One of the major problems in power system is the over line current from short circuit effect. It may cause in the electrical apparatus outages. Approach: Static Synchronous Series Compensator (SSSC) is a power electronic based device that has the capability of controlling the line current. This study applies the SSSC to decrease the over line current in power system during dynamic state. To verify the effect of the SSSC on over line current reduction, the mathematical model of power system equipped with a SSSC is presented. The variation curve of line current of the faulted system with without and with a SSSC is tested and compared in various cases. Results: The line current of the system without a SSSC is continuously oscillation and the maximum value is much more than the system with a SSSC. Conclusion: SSSC can decrease over line current in power system from short circuit effect.
