| 摘 要： | 为研究用于电阻型超导限流器的第二代(2G)超导带材的故障限流特性,本文对在该过程中带材的瞬态物理变化进行分析,结合2G超导带材的物理结构及成分配比,针对短时交流大电流冲击下超导体瞬间从超导态转变为有阻态过程,建立超导带材的物理模型。利用Matlab对该过程进行数字建模仿真,获得故障限流过程中超导带材的电流、电阻等系列参量的直观变化规律,并对上述物理模型进行校验,实验验证仿真结果的有效性。

| Abstract: | In order to study the fault current limiting characteristics of second generation(2G)superconducting tapes used in resistive superconducting fault current limiters,the transient physical changes of tapes are analyzed. Based on the physical structure and composition of 2G superconducting tapes,the physical model of tapes is estab-lished for instantaneous transition from superconducting state to resistive state of the superconductor under AC over -current.The digital modeling and simulation of this process is carried out by Matlab,and the parameters of the cur-rent and resistance of superconducting tapes are obtained.The validity of the model and simulation results are veri-fied by experiments. |
