Thyristor controlled series compensation(TCSC) has been an important controller among the flexible AC transmission systems(FACTS), while using TCSC for damping system sub-synchronous resonance (SSR) has been the emphasis on the academic and engineering. This paper introduced about SSR and TCSC, mainly analyzed the impacts of different control methods of TCSC on SSR. The methods include closed-loop constant impedance control, closed-loop constant current control and closed-loop constant power control. The time domain simulation based on PSCAD/EMTDP is adapted to analysis there different control methodologies on mitigating SSR.
