Description
With ReBCO tape conductors increasingly being applied in electrical machines, understanding their rich behaviour in terms of current distribution and AC loss under applied currents and – magnetic fields in environments that include ferromagnetic materials is crucial. Such behaviour is often simulated with commercial Finite Element Method (FEM) software using, among many other techniques, the H- and T-A formulations. As computationally efficient alternatives to such FEM formulations, integral methods such as the Partial Element Equivalent Circuit (PEEC) method and Brandt’s method have successfully been implemented for various cable- and coil lay-outs at the University of Twente.
In this work, we expand our 2D PEEC formulation to include also the effects of non-linear ferromagnetic materials in the vicinity of the superconductor. The ferromagnetic domain is resolved with the Magnetostatic Moment Method (MMM), which is then implicitly coupled with the PEEC formulation. In addition, the model is benchmarked against analytical solutions and the T-A formulation implemented in COMSOL Multiphysics, showing a good agreement for a wide range of cases.
