摘　　要：超导储能装置(SMES)的超导线圈在充电时,要求其充电速度比较快,同时要求电流超调量不能太大,保证磁体在超导态下运行。超导线圈电流达到稳态,SMES处于待机状态时希望电流保持恒定,以减少磁体电流变化带来的损耗。本文设计了主电路电气参数和控制电路-电流调节器,建立系统数学模型,并基于传统电流调节器进行了工程上的改进,最后对超导线圈充电过程进行了仿真、分析,得到开关元件及超导线圈的过渡过程曲线,为选择电力元件及设计超导线圈提供相关参数。When Superconducting coil of SMES is charged, the high speed chage is expected, at the same time the current over regulated should be low, so that the coil is under superconducting state. When the SMES is in holding state, the currentvaries little. The parameters of main circuit and the control circuit-current controller are designed, and improved based on traditional controller. Through modeling and simulating, the coil and the power switch unit can be analyzed.
