Influences of superconducting fault current limiter (SFCL) on superconducting generator in one-machine double-line system

Analysis of superconducting generator in single machine double-line infinite-bus transmission system equipped with SFCL's has been performed by use of EMTDC/PSCAD. When some faults occur in one transmission line, the SFCL in the fault line operates and then the peak fault current can be limited to expected value by use of a function of the SFCL. However, in some cases, the SFCL in the other sound line has been also proved to occasionally operate due to the interaction through each transmission line. Problems due to an installation of the SFCL's in such a model system and the influences on the superconducting generator have been pointed out by simulation analysis.
