This paper presents a roadmap to the application of AI techniques and big data for different modelling, design, monitoring, manufacturing and operation purposes of different superconducting applications. To help superconductivity researchers, engineers, and manufacturers understand the viability of using AI and big data techniques as future solutions for challenges in superconductivity, a series of short articles are presented to outline some of the potential applications and solutions. These potential futuristic routes and their materials/technologies are considered for a 10-20 years time-frame.

“…A DC cable project connecting PV system and Ishikari datacenter was constructed under a NEDO project [45]. As a new DC cable application, replacement of the railway feeder, which has been studied in Railway Technical Research Institute of Japan, has been attracting attention [46]. The energy saving effect is large in this application, because the power loss is small and there is no voltage drop, which allows reduction of the number of substations to maintain high voltage suitable for running.…”

It took longer time than initially expected for development of cuprate superconducting materials for practical applications. However, there are about 20 companies that manufacture and supply long conductors and bulk materials at present. Although various large‐scale projects have supported the process of material development, material and equipment developments have been progressing under the leadership of manufacturers in recent years. In this paper, current status of development of high‐temperature superconducting materials, including MgB2, which is classified as a high temperature superconductor, and their applications are summarized, along with the history, basic physical features and recent topics. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

The use of High Temperature Superconducting (HTS) cables as a technology is considered as key to increasing the power of the electrical grid while reducing the volume of installation. In addition, when transmission currents exceed a few kA, DC HTS cables significantly reduce power losses, rights-of-way and total system mass. This article describes the various studies that need to be carried out in order to correctly size HTS DC cables for the new railway network envisaged by the French company SNCF, which must consider ultra-urban needs. The process used to design DC cables for operating powers of 10, 20 and 30 MW at a nominal voltage of 1.5 kV using commercial (RE)BCO tapes is presented. In this sizing process, the critical current density Jc(B, θ, T) dependence of the superconducting tapes, the thermal properties of the materials and the different cooling modes are taken into account. Several solutions are suggested to ensure that the cable can withstand fault currents and reduce recovery time in the initial state. Finally, with the help of analytical models and industrial data, once the cables have been designed, the various system losses are reported as well as the power or size of the various auxiliary components.
