高温超导SMES磁体能量损耗的分析

Energy loss in the magnet of a HT_c SMES using for improving the stability of electrical power system

通过实验和仿真对35kJ/7kW传导冷却高温超导SMES磁体稳态运行和动态功率交换时的能量损耗进行了分析,讨论了功率交换时磁体各个主要部件能量损耗分布的特点,最后根据分析结论指出了现阶段降低传导冷却高温超导SMES储能磁体损耗的优化设计方向。

The energy loss of a conduction--cooled HTo magnet is analyzed, which is used in a SMES for improving the stability of electric power system. In steady state, there is little loss, but , during the period of energy exchange, loss are produced in superconducting coil and other constructure parts of the magnet. Loss distribution in the magnet is also discussed, and those results are very useful for the optimal design of the magnet.
