FEM-circuit co-simulation of superconducting synchronous wind generators connected to a dc network

Résumé

The work focuses on the electromagnetic modeling of a 15 MW hybrid High-Temperature Superconductor Synchronous Generator (HTSSG) for wind power application. It combines a superconducting (SC) rotor with a conventional stator. A particular interest is given to co-simulation, coupling a Finite Element Model (FEM) with an external electrical circuit. This is achieved by coupling COMSOL Multiphysics with Simulink through a Functional Mock-up Unit (FMU). The study uses the homogeneous T-A and J-A formulations of Maxwell equations alongside classical FEM techniques to account for features like moving mesh and nonlinear B-H curve. The FEM distributed variables such as current density, magnetic flux density, and local losses are computed. Similarly, global variables such as voltage, current, electromagnetic torque, and power quality are estimated in the circuit. These variables are compared for both formulations. It provides a reference to find the best-suited combination FEM-circuit when evaluating computational speed gain and numerical stability between formulations.
