| Abstract: | 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. |
