Abstract

The needs and expectations of the Danish electric utilities with concern to the prospective application potential of superconducting fault current limiter in the existing Danish electric utility system have been investigated by a questionnaire survey. In the present power supply network, the most obvious areas for application of SFCL technology are identified as a 10 kV bus-tie location of a 60/10 kV transformer substation and the feeder outlet location of 132 kV and 30 kV cables. The greatest prospective application of SFCL is anticipated to occur in the 132/150 kV transmission networks in the wake of system redesign and reinforcement. The survey has also shown that the utilities have a need for more information concerning the technical performance and economy of the SFCL, before they can take specific decisions on a possible introduction of SFCL into the network system
