Abstract

We investigated the analysis of operation mode of three-phase flux-lake type superconducting fault current limiter(SFCL). The structure of the integrated three-phase flux-lock type SFCL consisted of three-phase flux-lock reactor wound on an iron core with the same turn between coil 1 and coil 2 in each phase. When the SFCL is operated under the normal condition, the flux generated in the iron core is zero because the flux generated between two coils of each single phase is canceled out. Therefore, the SFCL's impedance is zero and the SFCL has negligible influence on the power system, However, if a fault occurs in any single-phase among three phases, the flux generated in the iron core is not zero any more. The flux makes elements of all phase-quench irrespective of the fault type, which reduces the current of fault phase as well as the current of sound phase.
