Abstract
This paper presents a hysteresis model for Type-II high temperature superconductor (HTS) by using simplified Preisach Model, in which the Preisach distribution function µk(�,�) is determined only based on the B H limiting loop. The nonlinear dynamic circuit model of the superconductor is established. In the circuit model, the hysteresis inducta nce and hysteresis loss described by using simplified Preisach Mode l are deduced. Applying the hysteresis circuit model, the currents flowing in different superconductor layers of high temperat ure superconducting cable are simulated, as well as the hysteresis loss of the superconducting cable. The simulation results are verified by comparison with the data recorded in literatur es. Finally, the influences of hysteresis on superconducting ca ble are analyzed and discussed.
