FC-TBSR Compensator for Reactive Power Compensation and Voltage Swell Mitigation

This paper introduces FC-TBSR, which is one of the controllers in flexible AC transmission system. The thyristor binary switched reactor contains thyristors which are connected in antiparallel which acts as bidirectional switch in series with a reactor and fixed capacitor connected across. The reactor banks are arranged in binary steps. Usually, FACTS devices are used for voltage regulation and reactive power compensation but it has some drawbacks like harmonics injection and it will not give fine voltage control because it has fixed values. To avoid and overcome these drawbacks, a new FC-TBSR compensator has been proposed.
