百千焦级高温超导环型SMES磁体设计研究

摘要

Toroidal SMES is the developing direction of HTS SMES. There have been many conceptual designs of HTS toroidal SMES, but whose energy storage capacities mainly concentrate on more than trillion joules. HTS toroidal SMES which have been constructed and tested in a power system only has an energy storage capacity of several kilo - joules. Considering that the development of HTS toroidal SMES is still at lab stage, this paper researched on the design of HTS toroidal SMES whose energy storage capacity was more the one hundred kilojoules by means of genetic algorithm ( GA) and FEM. The relationship between the number of unit coils n, inner diameter of unit coils d, the inner diameter of the toridal magnet D and the energy storage capacity E were discussed.%高温超导SMES磁体未来的发展方向是环型磁体,目前对高温超导环型SMES磁体的概念设计比较多,但储能量主要集中在兆焦级,真正制作完成并并网实验的储能量只有千焦级.文中立足高温超导环型SMES处于实验室研究阶段的现实,用遗传算法和有限元法结合的方法对百千焦级高温超导环型SMES磁体进行了设计研究,总结出了单元线圈数量n、单元线圈内直径d和环型磁体内直径D影响磁体储能量E的规律.
