Technical and economical benefits of superconducting fault current limiters in power systems

There is no doubt that superconducting fault current limiters (SFCL) will be used if their technical and economical benefits are high enough. Up to now a number of studies have been carried out to show suitable applications of SFCL but very few reports have been published on their technical and economical benefits in existing networks. This paper shows favourable places of SFCL in an urban network up to a voltage of 110 kV, lists technical benefits and calculates the economical savings. In the investigated network it was found that feeder locations of power stations and wind generators are the most economical places for SFCL.
