- Abstract
- The fault current limiting characteristics of DC dual reactor type superconducting fault current limiter (SFCL) using switching operation of high-T-C superconducting (HTSC) elements were analyzed. The suggested SFCL consists of a diode bridge, DC dual reactor with magnetic coupling and HTSC elements. Unlike the conventional bridge type SFCL, which requires the controller for the operation of the interrupter to prevent the continuous increase of fault current after a fault happens, this SFCL can be operated without the interrupter and the controller for its operation. In addition, despite different critical currents after a fault accident, the balanced power burden between HTSC elements can be achieved by the magnetic coupling between two coils of DC dual reactor. It was confirmed through the experiments for the fault current limiting characteristics that the suggested SFCL performed the advantageous current limiting operations compared to the conventional bridge type SFCL using HTSC coil.
