Abstract
Aim: development of a simultaneous model, calculation and analysis of heat losses of a superconducting CORC cable based on standard HTSC tapes and irradiated HTSC tapes in cyclic load modes for magnetic energy storage system.
Methods: the CORC cable based on industrial original HTSC tapes and HTS tape with defects from irradiation is considered; to describe the electromagnetic and thermal characteristics of the system are used following methods: the concepts of the macroelectrodynamics, the fundamentals of the applied superconductivity, the finite element method are used; the calculation is implemented in the COMSOL Multiphysics.
Results: a model was developed, the optimal cooling mode was determined in 5 load cycles, it was shown that the presence of artificial pinning centers can significantly improve the thermal stabilization of the system and leads to a reduction in heat losses with the considered cooling schemes.
Conclusion: the results can be used in the development of the magnetic energy storage system based on high-temperature superconducting composites (HTS).
