Abstract

This paper describes an optimal design method for SMES coils wound with high temperature superconducting tapes. Commonly, on the design stage of a SMES coil, its configuration is optimized to reduce the winding volume and the weight under taking into account the electromagnetic characteristics of high temperature superconducting tapes. The better configuration can be optimally designed to taken into account its thermal characteristics. So, we propose an optimal design method for SMES coils wound with Bi2223/Ag tape taking into account both electromagnetic and thermal characteristics. In this paper, the designs of 72 MJ toroidal SMES coil are investigated using the simulated annealing as an optimization method and the finite element method as a thermal analysis method.
