Critical Current, Critical Temperature and Magnetic Field Based EMTDC Model Component for HTS Power Cable

Before applying the high temperature superconducting (HTS) power cable to real utility network, system analysis should be performed using simulation tools. For the practical use of HTS devices in electrical power system, prior simulation analysis is very important. PSCAD/EMTDC simulation is one of the most popular and useful analysis tools for electrical power system. Unfortunately the model component for HTS power cable is not provided in the PSCAD/EMTDC simulation tool. In this paper, EMTDC model component for HTS power cable has been developed considering critical current, critical temperature, magnetic field, and recovery time constant which depend on the sorts of HTS wire. The numerical model of HTS power cable in the PSCAD/EMTDC was designed by using the real experimental data obtained from a real HTS 1G wire test. The utility application analysis of HTS power cable was also performed using the model component developed. The component for HTS power cable could be variously used when the power system includes HTS power cable, especially it will be readily analyzed by the PSCAD/EMTDC in order to obtain the data for the level of fault current, power flow, and power losses, and so on.
