摘要
给出了饱和铁心型高温超导故障限流器(HTSFCL)的结构模型,分析HTSFCL的原理,通过数学模型计算得到短路时的瞬态电流波形。利用磁路法和三维瞬态磁场-电路耦合法分别对瞬态过程进行仿真,并与样机试验结果进行对比。仿真结果验证了两种方法的正确性。针对短路时超导线圈过电压的问题,提出了使用磁屏蔽环的方法来改善。
The structure model of saturated core high temperature superconducting fault current limiter （HTSFCL） was given, and the principle of HTSFCL was analysed. The transient current waveform was calculated by the mathematical model at short circuit. The transient process was simulated by using magnetic circuit method and three-dimensional magnetic field-circuit coupling method, respectively. The correctness of the simulation methods was proved through the comparison of test results and simulation results. The superconducting coil overvohage problem was solved by using the magnetic shielding rings.
