摘要
超导限流储能系统(SFCL-MES)的能量以磁场的形式存储在超导磁体中,因此漏磁场对于 变电站的电磁干扰问题成为影响其应用的关键问题之一。文中对用于SFCL-MES的多种磁体结 构的漏磁场进行了分析与优化,以选择合适的磁体构型,便于SFCL-MES安装在变电站中。首先 对于超导限流储能系统磁体的漏磁场进行了勒让德多项式分析。在此基础上,对于多种磁屏蔽型 磁体构型,包括同轴同心、轴向排列、轴线平行组合磁体结构,以减小漏磁场和所用的超导线材最少 为目标,给出了优化模型,并采用序列二次规划(SQP)方法对模型进行求解。最后对优化结果进行 了比较分析。
Since the energy stored in superconducting fault current limiter-magnetic energy storage （SFCL-MES） exists in the form of magnetic field in the superconducting magnet, its stray field can bring serious electro-magnetic interference （EMI） with the substation. This has become one of the major problems for the application of SFCL-MES. The stray field of magnets with different configurations is analyzed and optimized to choose the magnet configuration for SFCL-MES. Based on the analysis on the stray field of magnets of SFCL-MES by Legendre polynomials, many schemes of SFCL-MES＇ s magnet with different configuration are given for reducing the stray field, such as coaxial and homocentric configuration, axially displaced solenoids configuration and axially parallel solenoids configuration. In order to minimize the stray field and superconducting cable for SFCL-MES, the paper proposes optimization schemes by the sequential quadratic programming （SQP） strategy with MATLAB/Optimization toolbox, and the optimized schemes are compared and analyzed.
