Finite Element Model of a Superconducting Generator for Aircraft Application Coupled to an External Electrical Circuit
Résumé
High temperature superconductors (HTS) are strong material candidates for the development of future electrical machines due to their high energy density at low AC losses resulting in greater electrical efficiency for lighter and compacter designs than traditional machines. The features are particularly appealing for transports. The present work focuses on the electromagnetic modelling of a superconducting synchronous generator for aeronautic applications with a particular interest in the coupling between Finite Element Model (FEM) and external electrical circuits. The FEM implements different formulations of the Maxwell equations, namely H-A, T-A and the classic A-V , which can also be combined with the H, to find the best suited combination FEM - electrical circuit for computation load reduction (time and memory). The external circuit simulates a power converter interconnecting the machine to the load. The performance of both the machine as a whole and the superconductor is evaluated for different load conditions.
