Résumé

In this century, the energy issue in the railway network is a major topic, between the new environmental reforms, especially for the reduction of CO2 emissions and the increase of the network power in order to respect the EN 50163 standard. All these constraints require the addition of power supply devices, moreover the DC traction lines are generally installed in areas where the urban density is important (Paris, Tokyo...). In other words, the insertion of conventional electrical equipment is becoming more and more difficult. The use of high temperature superconducting (HTS) cables as a technology is considered as a promising solution to increase energy efficiency and reduce the footprint constraints. In this paper, a 3D electromagnetic model is proposed to calculate the mutual and self-inductances of each pole of a designed cable for French railway network. Then, the behavior of the superconducting cable in realistic dynamic regime is presented using the Matlab-Simulink tool. In this simulation process, the dependence of the critical current Ic(T) of the superconducting tapes and the different operating modes (acceleration, braking) are considered.
