“…The successful test results have been also reported for 15 kV prototype [52]. AC-type SFCL (AC-SFCL) is another attractive idea which can be considered as a coreless inductive-type SFCL [53,54]. The operating principle of this concept is the same as the previous.…”

“…As a consequence, the T-A formulation is only suitable for cases where the influence of the parallel component of the field is negligible, examples of these kind of cases are the coils analyzed in [20,28,29]. The cases where the influence of the parallel component cannot be neglected, like the long solenoid presented in [36], cannot be addressed with this formulation.…”

The emergence of second-generation high temperature superconducting tapes has favored the development of large-scale superconductor systems. The mathematical models capable of estimating electromagnetic quantities in superconductors have evolved from simple analytical models to complex numerical models. The available analytical models are limited to the analysis of single wires or infinite arrays that, in general, do not represent actual devices in real applications. The numerical models based on finite element method using the H formulation of the Maxwell's equations are useful for the analysis of medium-size systems, but their application in large-scale systems is problematic due to the excessive computational cost in terms of memory and computation time. Then it is necessary to devise new strategies to make the computation more efficient. The homogenization and the multi-scale methods have successfully simplified the description of the systems allowing the study of large-scale systems. Also, efficient calculations have been recently achieved using the T-A formulation. In the present work, we propose a series of adaptations to the multi-scale and homogenization methods so that they can be efficiently used in conjunction with the T-A formulation to compute the distribution of current density and hysteresis losses in the superconducting layer of superconducting tapes. The computation time and the amount of memory are substantially reduced up to a point that it is possible to achieve real-time simulations of HTS large-scale systems under slow ramping cycles of practical importance on personal computers.

“…At the two ends of the solenoid, however, there is a substantial perpendicular component of the field (see figure 13), which causes very large AC losses. In [20] the authors report some calculation for a solenoid used as a shielded-core superconducting fault current limiter (SFCL) where the last turn has Magnetic field lines of the cross section of a cable carrying current. Due to the interaction between the fields generated by the various tapes, the field is mostly oriented in the 'good' direction, i.e.…”

A numerical model implemented in the open-source finite-element method FreeFEM program is presented, with the aim of introducing students to the calculation of AC losses in superconductors. With this simple approach, students can learn about the critical state model used to describe the macroscopic electromagnetic behavior of superconductors and the importance of different factors influencing the AC losses of superconductors.
