The two-dimensional modeling in the invention is simple and fast, the calculation amount is greatly reduced compared with that of a three-dimensional model, and the solution efficiency of the model is greatly improved. The two-dimensional model in the invention takes into account the influence of the three-dimensional structure of the conductor, the calculation result is more accurate and reliable, and a reference can be provided for the structural design of the superconducting cable. The method considers the layered structure ofthe superconducting tape, and the simulation analysis results of the conductor have high accuracy under different through current levels.
