Optimization of the terminations of an HTS cable operating on a DC railway network

Résumé

In recent years, there have been an increasing number of projects to use superconducting cables to address industrial challenges. In particular, the integration of superconducting cables into the network can be a solution to the challenges of increasing traffic on the railway network and regulatory issues. In this paper, the behavior of a single-pole superconducting cable and the losses of the whole installation, including terminations, in a daily scenario in the Paris area. To this end, we present a comprehensive approach to coupling a finite element (FE) model and an electrical circuit (EC) of the railway network with Simulink. The FE model is based on a cable model with a nominal current of 3.5 kA and a nominal voltage of 1.5 kV. This is the world's first cable project that will be installed on a commercial line of a railway network, near the Montparnasse station. The power law E(J) and the temperature and magnetic field dependence of the critical current density Jc(B,Theta) will be considered. The current flowing through the superconducting cable and terminations is simulated using a dynamic model of the railway network presented in [1] which includes an electrical model of the substation, a mechanical model to determine the traction force and train displacement and a variable line impedance model for the network. Finally, an energy balance will be presented, as well as details on the choice of the cooling system to ensure the proper functioning of the entire superconducting installation.
