摘要
本文针对使用YBCO带材的螺线管型SMES,使用Ansoft Maxwell建立了其电磁模型.考虑到YBCO带材临界电流的各向异性,利用Ansoft Maxwell场计算器建立了与线材呈40°角的最大磁场强度的函数.实现了YBCO磁体临界电流、实际运行电流及实际储能容量的快速准确的计算.变换了磁体形状变量空间,并利用参数化计算缩小搜索范围,以缩短优化算法的收敛时间.基于以上工作,结合Ansoft Maxwell提供的遗传算法优化工具,实现了对100KJ螺线管型超导磁体的设计,并对优化计算结果进行了分析.
Small superconducting magnet energy storage system(SMES)played an important role in the application of maintaining the stability of the smart grid.This paper contributed the electromagnetic model of small solenoid SMES using YBCO tape by Ansoft Maxwell.Considering anisotropy of the YBCO critical current,this paper made up the function of the maximum magnetic field intensity which has a 40°angel to YBCO tape in Ansoft Maxwell field caculator.These make the calculation of the YBCO magnets critical current,the actual running current and practical energy storage capacity rapidly and accurately.Transformed the magnet shape variable space,and made use of parametric calculation in order to narrow the search range as well as shortening the convergence time of optimization algorithm.Based on the above work,this paper designed and optimized a 100 kJ solenoid HTS magnet,and analyzed the optimization results.
