摘要：

We have proposed a "Flux-Lock" type high T-c superconducting (HTS) fault current limiter (FCL) composed of the flux-lock reactor with HTS element and the magnetic field coil circuit. In this FCL, the initial limiting current level can be arranged by setting inductance combination of the flux-lock coils and an ac magnetic field is applied to the HTS to get higher resistance only in a current limiting phase. This paper describes design guidelines for the HTS-FCLs. The impedances of the FCLs were expressed as a function of the product of the normal resistance and the square of the quench current level, which we have proposed to refer to as "quench power". Supposing the FCLs are introduced into the extra-high voltage transmission system and power distribution system, the "quench power" necessary for the FCLs to suppress the fault current under the required level was discussed.
