Abstract:To analyze the spatial and time-independent electromagnetic distribution and performance of high-temperature superconductor applications, finite element models are usually constructed for numerical analysis. In this study, T-A formulation and H formulation are considered for comparative analysis, and the basic principles are introduced respectively. The electromagnetic performance of 3D REBCO single tape and superconducting cable is discussed in terms of magnetic flux density, current distribution, and AC loss. According to the characteristics of different formulations, single tape, and triaxial three-phase superconducting cable models are established while related partial differential equations with boundary conditions are set up. The accuracy of AC loss in the 3D finite element model is compared with theoretical calculation and 2D analysis results.
