Two projects for high temperature superconducting (HTS) power cable have been carried out in Korea since 2001. One of them is a HTS cable project in DAPAS (Development of Advanced Power system by Applied Superconductivity technologies) program funded by the Ministry of Education, Science and Technology. In this project, LS Cable Ltd. (LSC) and Korea Electrotechnology Research Institute (KERI) jointly developed a 22.9 kV, 50 MVA, 3 phase, 100 m HTS cable using first generation (1G) HTS wire in 2006. The HTS cable system has been tested in a power test center of Korea Electric Power Corporation (KEPCO). LSC and KEPCO have been developing a 22.9 kV, 50 MVA, 3 phase, 500 m HTS cable system using second generation (2G) HTS wire since 2008, based on the technology of the DAPAS project. This project is called as GENI (Green Superconducting Electric Power Network at the Icheon Substation) project. The target of GENI project is to install and operate the HTS cable system in the Icheon substation located in near Seoul. In order to analyze the Icheon substation power system employing the HTS cable, an analysis model of the HTS cable is necessary. This paper describes the development of an analysis model for the 22.9 kV, 50 MVA HTS cable that will be applied to the Icheon substation in Korea.
Bibliographical noteFunding Information:
This project is funded by the Korea government Ministry of Knowledge Economy (MKE). LSC has developed a 22.9 kV, 50 MVA, 500 m, 3 phase HTS cable system using 2G HTS wire, 344B manufactured by AMSC. Fig. 2 shows the configuration of the HTS cable and the specifications of the HTS cable are presented in Table 2  . KEPCO installed the HTS cable system at the secondary side of the fifth main transformer in late 2010 and will operate the system at the live grid, the Icheon substation in 2011 after some tests. Fig. 3 shows the one-line diagram and the layout for the application of the HTS cable to the Icheon substation. The role of KERI is to design the protection system of the Icheon substation and analyze the power system.
