Optimization of toroidal superconducting magnetic energy storage magnets

摘要

The paper presents an engineering and economic model for the optimization of toroidal superconducting magnetic energy storage (SMES) magnets. The optimization is applicable to magnets wound with cable-in-conduit conductor conductors. The model includes considerations of stability, quench protection, structural requirements, etc., in addition to cost models for materials and fabrication. As an example, the model is used to optimize a SMES magnet. The paper presents comparisons between magnet designs based on Nb3Sn at 4.2 K and NbTi at 1.8 K. It is shown that the Nb3Sn option is preferable for this application. The model is used to optimize the design based on different criteria, such as cost, volume, and footprint.
