“…For such a geometry the local components of the magnetic field need to be computed for each tape taking into account its orientation with respect to the global coordinate system. For this purpose we have implemented an additional subroutine in order to enable the software to calculate the two local components of the field at each FEM node, before computing the critical current density and the power index according to (1) and (2).…”

“…3 shows the magnetic field distribution in the superconducting part of the cable for a transport current equal to 3800 A (peak value). The magnetic field produced by the transport current is in the order of 20-60 mT and causes current density degradation according to (1). Even if the direction of the field is almost parallel to the wide side of the tapes, the field magnitude is sufficient to reduce the critical current density by 15-30% in the different layers.…”

“…It can be used also to study how the transport current and the ac losses are shared by the different layers of a high-(HTS) superconducting cable for different working conditions. HTS cables consist of different layers of superconducting tapes wound helicoidally around a cylindrical former [1]. The layers have different winding direction and twist pitch for more even distribution of the transport current among them.…”

The finite element method has been employed in order to simulate the behavior of a HTS cable for transport current applications. The model includes an anisotropic dependence of the critical current density and power index on the local magnetic field, whose magnitude is nonnegligible and determines the effective critical current of the cable. The cable consists of four electrically insulated layers, each of them composed by 20 superconducting tapes, providing a total critical current of about 4 kA. In order to obtain a uniform repartition of the current among the layers, a sufficiently high contact resistance has been inserted in the electric circuit. The ac losses and the field distribution have been computed. A comparison is also made with a simple electric model of a HTS cable.

“…However, the upper field limit of ~ 1 T at 77 K due to the pancake vortex disintegration of magnetic flux lines (see Fig. 7) [327] restricts the LN 2 operation of Bi-2223 tapes to low-field applications such as cables [328,329] or transformers. For extremely high magnetic field applications at low temperature operation, Bi-2212 conductors are economically more attractive than Bi-2223 tapes due to simpler processing and thus lower fabrication cost [330].…”

“…In [61], the layout of a cable cooled by LN 2 is addressed using the VEM model to predict both its steady-state and transient behaviour. The model was applied to a cable of the Electric Power Research Institute [62]. The power generation within the cable is considered there by properly accounting for the current-voltage characteristic of the HTS tapes.…”

An overview of the main peculiarities of the models currently available in literature for the thermal-hydraulic analysis of the cooling of the HTS power transmission cables, mainly in nominal operating conditions, is performed. Several models address specific issues such as the temperature distribution along or across the cables, and their pressure drop, typically with a simplified approach. The verification and validation of the models has not been systematically addressed so far. From the analysis of the available literature, the lack of a general model, capable to address thermal-hydraulic transients for the cooling of the different possible cable designs, with capability to catch both the behaviour of the cable solid components and different cryogens, is highlighted. The main ingredients that such general thermal-hydraulic model should not miss are presented, also based on the know-how on, and comparison to, similar tools for LTS cables for nuclear fusion applications.
