Abstract

This paper outlines a systematic procedure for the design of a toroidal magnet for Superconducting Magnetic Energy Storage System and presents the optimum design for a 10 MJ class high temperature superconductor (HTS) magnet. The main magnetic component which influences the maximum critical current was investigated. Stray field and operating current needed in a toroidal magnet with different number of elemental coils were compared too. Based on above analysis, both electromagnetic and mechanical design objects were considered when optimizing the volume of HTS Superconducting magnet with optimal number of toroidal elements with Finite Element Method. Parameter surveys of the magnetic fields and electromagnetic stress applied to the HTS magnets were carried out and a suitable magnet dimension with low inductance and high current was studied. The results verify that the double pancake type is more favorable for actual design and operation.
