Abstract
Rising short-circuit fault current levels is one of the
problems associated with the increased presence of distributed
generation (DG) in electrical networks. A fault level management
system involving superconducting fault current limiters (SCFCLs)
is a potential solution to this issue. The typical applications
of SCFCLs and their advantages over traditional fault current
limitation measures are discussed. However, several technical issues
remain, relating to: SCFCL post-fault recovery time; network
control and protection; and maloperation of the SCFCL due to
non-fault transient currents, such as transformer inrush. Initial
solutions to these problems, involving a distributed software-based
fault level management system, are presented.
