摘要
超导磁体是超导储能-限流系统(SMES-FCL)中最为核心的部件,它运行于复杂电磁环境中,电磁设计是整个磁体设计中最为重要的环节。文中结合1G和2G高温超导带材的电磁特性,采用两种带材混合绕制磁体的技术方案,运用有限元方法(FEM)对1MJ高温超导磁体的电磁结构和特性进行仿真分析和研究。经过仿真与优化,综合带材用量、制冷成本和运行成本以及在脉冲和限流等极端情况下所需安全裕度等多种因素,完成磁体的电磁优化设计。
Superconducting magnets are the most central parts in superconducting magnetic energy storage - fault current limiting system （SMES -FCL）. It runs in a complex electromagnetic environment. Electromagnetic design is the most important part in the superconducting magnet design. In this paper, considering the electromagnetic characteristics of 1G and 2G HTS tapes, the hybrid magnet technology was used. The finite element method （FEM） was used for the simulation analysis and research on electromagnetic structure and properties of the 1MJ HTS magnet. After simulation and optimization, the electromagnetic optimal design of the 1MJ HTS magnet was completed with considering the tape dosage, cooling costs, operating costs and other factors, such as a safety margin in the pulse and limiting cases.
