AN INVESTIGATION OF INTEGRATED POWER FLOW CONTROLLER WITH POWER CONTROL METHODS ENHANCED BY SERIES COMPENSATION CONTROL
Catherine T J S Ramkumar
The Unified Power Flow Controller (UPFC) is a multipurpose Flexible AC Transmission System which will improve the performance of a transmission line. The most preferred method of control of the series converter is power control. Alternate methods as series compensation method, phase shifter method, transformer like the control also finds their role in the control of the UPFC converters. This paper demonstrates the effectiveness of UPFC by employing a combination of control techniques integrated with series compensation control in improving the performance of the transmission line. It is shown that instead of keeping any one control method alone for controlling the performance of the line, if two methods are simultaneously implemented, there is marked improvement in the performance of the transmission system.
