Abstract
The application of superconducting fault current limiters (SCFCLs) in power systems isvery attractive because SCFCLs offer superior technical performance in comparison toconventional devices to limit fault currents. Negligible impedance at normal conditions,fast and effective current limitation within the first current rise and repetitiveoperation with fast and automatic recovery are the main attributes for SCFCLs.In recent years there has been a significant progress in the research and development (R&D)of SCFCLs. This paper gives an extended review of different SCFCL concepts, SCFCLapplications and the R&D status. Within the first part of this paper the most importantSCFCLS and, to a limited extent, non-superconducting fault current limiter (FCL)concepts are explained and compared. The second part reviews interesting SCFCLapplications at the distribution and transmission voltage level and the third part shows indetail the R&D status.It can be summarized that SCFCLs are, at present, not commercially available but severalsuccessful field tests demonstrated the technical feasibility of SCFCLs. First distributionlevel applications are expected soon. Considerable economical and technical benefits can beachieved by applying SCFCLs at the distribution and transmission voltage level.
