Abstract

Three-phase multi-layer high temperature superconducting coaxial (TPMHTSC) cable is being actively studied due to advantages such as the reduction of the amount of superconducting wire usage and the miniaturization of the cable. The electrical characteristics of TPMHTSC cables differ from those of conventional superconducting cables, so sufficient analysis is required to apply them to the actual system. In this paper, the authors modeled 22.9 kV, 60 MVA TPMHTSC cable and analyzed the transient characteristics using a PSCAD/EMTDC-based simulation. As a result, when a fault current flows in TPMHTSC cable, most of the fault current is bypassed through the copper former layers. At this time, the total cable temperature increased by about 5 K. Through this study, we can verify the reliability of the TPMHTSC cable against the transient state, and it can be helpful for the practical application of the cable in the future.

3상 다층 고온 초전도 동축 케이블은 초전도 선재 사용량의 감소 및 케이블의 소형화와 같은 이점 때문에 활발히 연구되고 있다. 3상 다층 고온 초전도 동축 케이블의 전기적 특성은 기존 초전도 케이블과 차이를 가지므로 실제 시스템에 적용하기 위해 충분한 분석이 필요하다. 본 논문에서는 PSCAD/EMTDC 기반 시뮬레이션을 통하여 22.9 kV, 60 MVA급 3상 다층 고온 초전도 동축 케이블을 모델링하고 과도 특성을 분석하였다. 결과적으로 3상 다층 고온 초전도 동축 케이블에서 고장전류가 발생하면 대부분의 고장전류가 구리 포머층을 통해 우회한다. 이때, 케이블 전체 온도는 약 5 K 증가하였다. 본 논문을 통해 3상 다층 고온 초전도 동축 케이블의 과도 상태에 대한 신뢰성을 확인할 수 있으며 향후 케이블의 실 계통 적용에 도움이 될 수 있다.
