Protection Coordination to Protect the Superconducting Cable in Icheon Substation

이천 변전소 초전도 케이블 보호를 위한 보호협조 방안에 관한 연구

Based on the several advantages of high-temperature superconducting cable, there are many researches about HTS cable. In the aspect of power system engineering, since it has very low impedance, approximately zero, it is profitable for large capacity distribution line into the large scale load. In the step of its verifications, the HTS cable had been installed in Icheon substation and operated. In this paper, the protection coordination for Icheon substation had been designed and verified using PSCAD/EMTDC.
