Description
Summary:In response to the combined effects of growing energy demand and the impact of de-regulation of the electrical energy industry, pro-active utilities are ensuring flexibility and robustness of their networks, by upgrading or installed capacity in both transmission and distribution. In this regard, high-temperature superconducting (HTS) cable systems offer advantages where space, thermal capability and environmental conditions constrain capacity. To facilitate the transition of HTS cable technology from the laboratory to the field, Pirelli Cables and Systems, EPRI, Detroit Edison, a DTE Energy Company, ASC, and the US DOE have undertaken a program which will result in the demonstration of a HTS power cable to deliver electricity in a utility network. This program will demonstrate a retrofit upgrade application of the Warm Dielectric HTS cable design in the Detroit Edison utility network, and involve the design, engineering, installation, test and routine operation of a 24-kV, 100 MVA, 3-phase cable system. The original circuit, comprised of three parallel circuits of conventional cables, will be replaced by a single circuit of HTS cables which will provide the same power capacity. Each HTS cable will carry 2400 A RMS, a level triple the capacity of original cables powering this circuit. This paper addresses the issues relating to the field application of HTS cables in the context of the demonstration program.
