In this paper, the influence of superconducting fault current limiter (SFCL, flux-coupling type) on power system transient stability is studied in detail. The influence of SFCL to transient stability of power system is studied using a model of single generator infinite bus system, different transient stability calculation results gotten with and without SFCL and with model system in different fault conditions are compared. The results show that the SFCL can effectively reduce the transient swing amplitude of rotor and extend the critical clearance time, and the application of SFCL in the power system can help to enhance its transient stability.
