Results from the Danish High Temperature Superconducting Power Cable Project

Abstract

For the first time, a high temperature superconducting (HTS) demonstration cable system has been installed in a utility network supplying electricity to consumers. The cable is a 30-m long, 30kVrms, 2, 000Arms cable, installed in the network of Copenhagen Energy at a substation supplying approximately 50, 000 customers. The purpose of the cable installation is to obtain installation and operating experience with this type of cable. The cable system has been in operation since May 28th 2001, and the first operating experiences of the cable have been satisfactory. The cable has been in operation for more than one year, and the cable has during the first year supplied 101, 000MWh of energy to the customers.
