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.

The Impact

Superconducting fault current limiters (SFCLs) are attracting increasing attention due to their potential for use in modern smart grids or micro grids. Thanks to the unique non-linear properties of high-temperature-superconducting (HTS) tapes, an SFCL is invisible to the grid with faster response compared to traditional fault current limiters. The quench recovery characteristic of an HTS tape is fundamental for the design of an SFCL. In this work, the quench recovery time of an HTS tape was measured for fault currents of different magnitudes and durations. A global heat transfer model was developed to describe the quench recovery characteristic and compared with experiments to validate its effectiveness. Based on the model, the influence of tape properties on the quench recovery time was discussed, and a safe margin for the impact energy was proposed.
