초록

본 논문에서는 본 저자가 제안한 직렬연결된 두 코일의 자기결합을 갖는 초전도 전류제한기의 사고전류제한 시뮬레이션과 실험을 수행하였다. 평상시에는 두 코일로부터 발생되는 자계는 상쇄되지만 사고가 발생되면 초전도 소자의 저항발생으로 더 이상 두 코일로부터 자계는 상쇄되지 않게 되고 제한기 임피던스 발생으로 고장전류가 제한된다. 제안한 자기결합을 이용한 초전도 전류제한기의 두 코일의 인덕턴스비를 조절함으로써 제한기의 동작전류와 임피던스는가 향상될 수 있음을 시뮬레이션과 실험을 통해 확인할 수 있었다.

The simulation and experiment for the fault current limiting characteristics of the superconducting fault current limiter (SFCL) using the magnetic coupling of series connected two coils were performed. The magnetic fluxes generated from two coils were canceled out during a normal time. However, the resistance generation of high-Tc superconducting (HTSC) element after a fault occurrence allows the magnetic fluxes of two coils and contributes to the fault current limiting operation. Through the computer simulation and the current limiting experiment for this SFCL, the operational current and the limiting impedance of the SFCL could be confirmed to be improved by adjusting the inductance ratio of two coils.
