Flexible AC transmission systems: A status review

Abstract

With the availability of high power semiconductor switches with turn-off capability, voltage source converter based controllers for power transmission system applications have become a reality. Prototypes of some second generation Flexible AC Transmission System (FACTS) controllers like TCSC and STATCON have been installed. This paper presents a review of the progress in FACTS. A generalized description of FACTS controllers is also presented. © 1997 Indian Academy of Sciences.
