摘要:

研究了超导磁储能磁体在动态载荷作用下的热稳定性,基于有限元方法构建了直接冷却高温超导磁储能磁体的数学模型,进行了充放电过程磁体温度场仿真,研究表明,在间断载荷作用下磁体具有较好的热稳定性,在连续载荷作用下,控制励磁电流速度和间隔时间可保证磁体的运行温度在30 K以下。

Abstract:

To investigate dynamic thermal stability of SMESsuperconducting magnetic energy storagemagnetmathematics model of the HTShigh temperature superconductivitymagnet was established based on finite element method(FEM).Simulation of temperature field was carried out when magnet was charged and discharged.The research results showed that when the magnet was excitedthe hysterics loss is the main part of power lossand contributes to temperature rise.The result of simulation shows that the magnet is provided with favorable thermal stability on interrupted load and ensured operating temperature under 30 K by controlling rate and alternation time of excitation current on continuum load.
