D. Murali, Dr. M. Rajaram . Article:Active and Reactive Power Flow Control using FACTS Devices. International Journal of Computer Applications. 9, 8 ( November 2010), 45-50. DOI=10.5120/1403-1892
Flexible alternating current transmission systems (FACTS) technology opens up new opportunities for controlling power and enhancing the usable capacity of present, as well as new and upgraded lines. The Unified Power Flow Controller (UPFC) is a second generation FACTS device which enables independent control of active and reactive power besides improving reliability and quality of the supply. This paper describes the real and reactive power flow control through a transmission line by placing the UPFC at the sending end of an electrical power transmission system. The power flow control performance of the UPFC is compared with that of the other FACTS device called Static Synchronous Series Compensator (SSSC). Simulations are carried out in Matlab/Simulink environment to validate the performance of the UPFC.
