Abstract

Because of the advantages such as the zero electrical resistance effect that disappears in the vicinity of the absolute temperature and the magnetic levitation effect, the superconducting applications are being tried in a variety of fields. But, those have faced many difficulties in the practical use because of the difficulty for the realization of the superconducting critical temperature. Recently, however, because the high-temperature super conductors was discovered newly which show superconductivity more than $30^{\circ}K$, the application researches based on it are being tried in various fields. Therefore, this paper examines the possibilities and issues by surveying the high temperature superconducting applications to electrical power system.

초전도 현상은 절대온도 부근에서 전기적 저항이 사라지고 자기부양 효과를 보이는 등의 장점 때문에 다양한 분야에서 적용이 시도되고 있지만 초전도 임계온도를 실현하기 위한 어려움 때문에 실용화에 많은 어려움을 겪어 왔다. 하지만 최근 $30^{\circ}K$ 이상에서 초전도 현상을 보이는 고온 초전도체가 발견됨으로서 다양한 분야에 대한 적용연구가 시도되고 있다. 따라서 본 논문에서는 최근 각광받고 있는 고온 초전도체의 전력계통 적용 사례들은 조사, 분석하여 그 가능성과 문제점들을 살펴보고자 한다.
