Abstract :
A case study of a 450 MVA, 132 kV high temperature superconducting (HTS) power transmission cable has been carried out. In the study, a superconducting cable system is compared to a conventional cable system which is under construction for an actual transmission line in the Danish grid. The study considers the design and development of a calculation model for an HTS cable system including auxiliary facilities. From calculations of the selected transmission line, conclusions on the feasibility of HTS cables in Denmark are made. HTS cables appear to be feasible in Denmark. Calculations indicate that HTS cables will be less expensive for high power ratings, have lower losses for lines with a high load, and have a reduced reactive power production. The use of superconducting cables in Denmark accommodate plans by the Danish utility to make a substantial conversion of overhead lines to underground cables.
