AC Losses Modeling in ReBCO Superconducting Coils Using the Volume Integral Method

Résumé

This paper presents a fast and efficient modeling approach based on the volume integral method for the characterization of AC losses in high-temperature superconducting coils made of second-generation Rare-earth Barium Copper Oxide (ReBCO) tapes. Three modeling strategies are investigated and compared, considering the detailed multilayer tape configuration, the homogenized tape configuration, and the simplified single-layer superconducting tape representation. These approaches aim to evaluate the impact of geometrical and electromagnetic simplifications on the accuracy of the results while significantly reducing computational time. In particular, the homogenization of the electromagnetic properties of the tape is explored to accelerate simulations without compromising the accuracy of key physical quantities such as AC losses and current density distribution. The modeling results are compared to measurements.
