超電導故障電流限流器の故障電流抑制効果とその仕様決定に関する考察

抄録

Desingn of power systems for meeting increase of electric power demands is be-coming more difficult and complex. One of the reasons is increase of the fault current. As one of the most effective methods for suppressing the fault currents, installation of fault current limiters are expected.For the above purpose, superconducting fault current limiters(SFCL's) are being developed.We have already given analitical solutions on fault current in power systems with SFCLs.
This paper discusses determination of specifications of SFCLs, and besides. effects of limiting the fault currents due to SFCLs by use of the model systems of one machine-infinite bus with single and parrallel transmission lines.
