Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a second embodiment of a superconducting fan control method according to the present invention, the method specifically includes:
step S201, when the superconducting generator 3 inputs the electric energy generated by the superconducting generator 3 during operation to the power grid 7, the controller 5 obtains the operation temperature of the superconducting generator 3 and the temperature change rate in a set period in real time; the operation of the superconducting generator 3 is realized by the driving of the fan gear unit;

in the specific implementation, under the condition that the superconducting fan system normally operates, the fan 1 drives the gear box 2 to operate, and then the gear box 2 drives the superconducting generator 3 and the normal-conduction generator 6 to operate. Since the power generation efficiency of the superconducting generator 3 is higher, the power supply of the normal-conduction generator 6 to the refrigeration unit 4 is preferentially ensured during operation, so that the refrigeration unit 4 can continuously supply cold to the superconducting generator 3. Meanwhile, the controller 5 monitors whether the output power of the superconducting generator 3 reaches the rated power or not in real time, and if so, the normal-conduction generator 6 is allowed to output power to the refrigeration unit 4 and also to output power to the power grid 7.

the refrigerating unit 4 outputs cold energy to the superconducting generator 3 through the restarting power supply;
when the restart temperature of the superconducting generator 3 is detected to reach the preset temperature, the superconducting generator 3 is driven to operate again under the driving of the gear structure.
In the specific implementation, when the superconducting fan system is restarted after being stopped, the fan 1 drives the gear box 2, then the gear box 2 drives the superconducting generator 3 and the normal-conduction generator 4 to operate, at the moment, the superconducting generator 3 does not output electric energy generated during operation to the power grid 7, the superconducting generator 3 does not do work outwards and does not generate heat, at the moment, the normal-conduction generator 4 is started, a restarting power supply is provided for the refrigerating unit 4 through the controller 5, and the refrigerating unit 4 can provide cold energy for the superconducting generator 3. When the temperature of the restarted superconducting generator 3 is lower than the preset temperature, it indicates that the superconducting generator 3 can normally operate, and at the moment, the superconducting generator 3 can operate again under the driving of the gear structure.
In the superconducting fan control method provided by the embodiment of the invention, when the superconducting generator inputs electric energy generated by the superconducting generator during operation to a power grid, the controller acquires the operation temperature of the superconducting generator and the temperature change rate in a set period in real time; the operation of the superconducting generator is realized by the driving of the fan gear unit; the controller judges whether the output power of the superconducting generator reaches the rated power; if not, the controller prohibits the normally-conducting generator from inputting the electric energy generated by the normally-conducting generator during operation to the power grid; the operation of the normally-conducting generator is realized by the driving of the fan gear unit; and if so, the controller determines whether to adjust the cold of the refrigeration unit to the superconducting generator according to the operating temperature and the temperature change rate. Therefore, the normal-conduction generator can control the running temperature of the superconducting generator in real time under the control of the controller, and the restriction of a superconducting fan system on a power grid is eliminated.
