摘要

第二代高温超导带材因其较高的临界电流密度以及良好的机械特性,近年来在超导研究领域得到极大关注。由REBCO带材组成的高温超导导体在液氮温度下的零电阻特性使其在超导输电领域具有巨大的潜力。从安全角度看,高温超导导体的失超保护研究是其获得广泛应用的一个关键问题。本文建立了准各向同性超导股线的三维失超仿真模型,耦合了电场、磁场和温度场,模拟了不同运行电流以及不同点状热干扰能量下超导股线的失超行为,求解出了股线的温度、电流密度以及磁场分布,得到了准各向同性高温超导股线的最小失超能（MQE）以及失超传播速度（QPV）,对超导装置的失超保护具有重要意义。本文对准各向同性超导股线建立的三维失超模型也可以应用到其它结构的高温超导导体的失超研究中。

Abstract：

With the development of the second generation (2G) high temperature superconductors (HTS) and the progress of cryogenic technology, 2G HTS has been widely applied in superconducting power technology due to its excellent mechanical properties, complete diamagnetism and zero resistance characteristic at liquid nitrogen temperature. However, the practical application of HTS faces the key issue: the quench behavior of HTS, which is mainly embodied in the minimum quench energy (MQE) and quench propagation velocity (QPV). The quench characteristics of quasi-isotropic superconducting (Q-IS) strand triggered by a point thermal disturbance are studied here, as well as the effects of different operating currents. It is of great significance for quench detection and protection of HTS devices in power systems.
Firstly, the structure and parameters of the superconducting strand used in the simulation model are described in detail, and the geometric model of a 140 mm long Q-IS strand immersed in liquid nitrogen is established. Then, considering the effect of the self-magnetic field, a 3D electric-magnetic-thermal simulation model is established to study the thermal stability of the strand based on the finite element method (FEM). At the beginning of the simulation, the operating current is applied to the HTS strand until the strand operates stably, then a thermal pulse is added in the center of the strand to simulate a point thermal disturbance. The thermal disturbance power is constant during the application of the thermal disturbance with the duration of 200 ms.
The thermal stability simulation results show that while the operating current is 3 000 A and the disturbance energy is 1.40 J/mm³, the strand shows an obvious quench recovery behavior, which means 1.40 J/mm³ doesn't reach the MQE of the strand. While the disturbance energy increases to 1.48 J/mm³, the quench region diffuses continuously as the time goes on, resulting in quench propagation behavior of the strand. Under this operating current, the MQE of the superconducting strand is 1.48 J/mm³, and the QPV is 0.79 cm/s. Then MQEs and QPVs under other different operating currents are simulated by the same method. It can be seen that the MQE of the Q-IS strand decreases from 2.17 J/mm³ to 1.04 J/mm³, and the QPV increases from 0.61 cm/s to 1.45 cm/s when the operating current increases from 2 600 A to 3 400 A.
Results also show: the MQE of the Q-IS strand decreases with the increasing of operating current, and the QPV increases with the increasing of operating current. The thermal stability of the Q-IS strand can be significantly improved by the current sharing of the copper sheath. However, the size designing of the copper sheath should consider the strand's QPV as well, because it shouldn't be too small to miss the quench detection time of the protection device. The electric-magnetic-thermal simulation model established in this paper can also be extended to study the thermal stability of Q-IS strands in external fields and other superconducting strands.
