Experimental study on the Unified Power Flow Controller
AbstractThis paper presents the results of experimental study on the performance of a Unified Power Flow Controller (UPFC), one of the FACTS (Flexible AC Transmission Systems) controllers. A laboratory‐scale UPFC was manufactured and installed on a laboratory electric power system to investigate its multifunctional capabilities as a power flow ...

Simulation study of unified power flow controller
The increasing complexity of ac power networks requires a high-performance power flow control system in order to obtain the desired power flow and enhance static and dynamic stability. One of the most effective power electronic systems to satisfy these requirements is a UPFC (Unified Power Flow Controller) employing self-commutated converters ...
