Evaluation of 2nd generation superconducting tapes as FCL elements.
Recently, our team succeeds in FEM modeling of high temperature superconducting fault current limiters (FCL) elements. By introducing a saturated E-J relation and taking into account the temperature dependence of the electrical parameters, the current limitation phase had been numerically simulated and results are in good agreement with measurements made on real samples. Based on our numerical modeling knowledge, we want now to study the electrical and thermal behavior of FCL elements made with emerging “commercial” coated conductors. The aim of this proposed project is to first identify the conductors resulting of different manufacturing process, and collect their electric and thermal properties. Then the work would be to simulate these conductors as FCL elements. The results will be decisive for the choice of the conductor in future FCL projects.
The student will be familiar with last conductors fabrication techniques, and will practice multiphysics Finite Element Modeling.
