Description
Liquid Hydrogen and Superconducting Magnetic Energy Storage (LIQHYSMES) system based on electric-hydrogen conversion and superconducting magnetic energy storage is one of the important development directions of composite energy storage technology. As an important electromagnetic energy storage unit of the system, the thermal stability of LIQHYSMES magnet is crucial for the safe operation of the system. Currently, there are two main cooling methods for LIQHYSMES magnets, namely immersion cooling and conduction cooling, but have the disadvantages of difficult pressure resistance design and low heat transfer efficiency, respectively. The object of this paper is a 30MJ/5MW LIQHYSMES magnet cooled by liquid-cooling plates. Thermal stability analysis is carried out considering the AC loss of superconducting magnet and eddy current loss of liquid-cooled plates.
