직렬 또는 병렬연결된 두 코일의 자기결합을 이용한 초전도전류제한기의 PSCAD/EMTDC 모델링을 통한 동작특성 분석

The operational characteristics of superconducting fault current limiter (SFCL) using magnetic coupling of series or parallel connected two coils were analyzed through the PSCAD/EMTDC simulation. This type SFCL consists of a high-Tc superconducting (HTSC) element and two magnetically coupled coils with series or parallel connection on the same iron. Through the modeling of two magnetically coupled coils and the HTSC element, the fault current limiting characteristics of these types of SFCLs, which were dependent on the winding direction and the winding structure of two coils, could be compared each other.
