摘要
提出了一种高温超导带材的故障电流冲击模型的建立方法,该方法以超导带材的数学模型为基础,用可变电阻模拟带材的阻值变化情况;搭建了带材的电路模型,编写了电阻值的计算程序,将PSCAD/EMTDC和MATLAB通过接口程序连接到一起进行联合仿真;得到了大电流下,高温超导带材失超过程中的电流、电压及温度的波形图,并对其进行了分析。对超导带材进行了交流测量实验,并将实验得到的波形和仿真波形进行了对比和分析。
In this paper,a method was proposed for establishing the electric circuit model of the HTS tape under the fault current based on the mathematic model of the tape.The variable resistance of the tape could be simulated using a variable resistor.The electric circuit model was built,and the calculating program of the resistance was written.Co-simulation was done by linking MATLAB with PSCAD/EMTDC,and the waveforms of the voltage and temperature of the tape under fault current were gotten and analyzed.Experiment was done and the results were analyzed.
