Abstract: The present disclosure relates to a superconducting power supply system which may comprise: a superconducting cable connected between terminals; a recovery pipe forming a closed loop with the superconducting cable to recover a liquid coolant of the superconducting cable; a pump for providing a circulating pressure of the liquid coolant through the recovery pipe; a refrigerator for maintaining a temperature by cooling the liquid coolant; and a superconducting fault current limiter for maintaining the temperature of a superconducting element immersed in a supercooled liquid coolant by introducing the liquid coolant recovered through the recovery pipe.
