Voltage Level Improving by Using Static VAR Compensator (SVC)

This paper presents the potential applications of flexible AC transmission system (FACTS) controllers, such as the static VAR compensator (SVC), using the latest technology of power electronic switching devices in the fields of electric power transmission systems with controlling the voltage and power flow, and improving the voltage regulation. Again, the static VAR compensators are being increasingly applied in electric transmission systems economically to improve the post-disturbance recovery voltages that can lead to system instability. A SVC performs such system improvements and benefits by controlling shunt reactive power sources, both capacitive and inductive, with high-tech power electronic switching devices. This work is presented to solve the problems of poor dynamic performance and voltage regulation in an 115KV and 230KV transmission system using SVC.
