Abstract: The present disclosure relates to a cooling control device for a superconducting fault current limiter, the cooling control device comprising a superconducting fault current limiter for cooling a saturated liquid coolant with a freezer to maintain a temperature of a subcooled liquid coolant in which a superconducting element is immersed, a pressure sensor for detecting a pressure of a second container in which the saturated liquid coolant of the superconducting fault current limiter is accommodated, and a control unit for estimating a temperature of the saturated liquid coolant by using a result of detecting the pressure of the pressure sensor, and controlling a temperature of the freezer depending on the estimated temperature of the saturated liquid coolant.
