  1. 1. Synchronous Voltage Reversal Control of Thyristor Controlled Series Capacitor

    Author : Lennart Ängquist; KTH; []
    Keywords : ThyristorControlled Series Capacitor; TCSC; FACTS; reactive power compensation; boost control; phasor estimation; Quantitative Feedback Theory; subsynchronous resonance; SSR;

    Abstract : Series compensation of transmission lines is an effectiveand cheap method of improving the power transmission systemperformance. Series capacitors virtually reduces the length ofthe line making it easier to keep all parts of the power systemrunning in synchronism and to maintain a constant voltage levelthroughout the system.
