开发了高温超导金属绝缘多模块/多双饼线圈中失超的最详细的第一原理仿真模型，该线圈缠绕有REBCO涂层超导体/带和普通金属带（共绕）。由于所有REBCO匝和共绕匝沿着与外部电路以及有源和无源失超保护系统之间的电感耦合和横向电接触，它使人们能够模拟线圈薄煎饼的微妙多匝结构中的正常区域传播或非传播。在这样做时，多模块线圈的结构被表示为“直线等效”电路，分支多层多矩形平面网格，这便于使用标准电路微分方程和基尔霍夫规则的数学公式。采用瞬态非线性综合热传导方程来模拟相同细节水平的现象的热部分。所有这些都使该模型成为金属绝缘，稳定和/或加强多模块线圈的有效设计工具。在6模块无绝缘（NI）测试线圈，使用不锈钢薄共绕失超的参数研究，进行了识别模型的可能性。横向接触电阻率对镍线圈失超行为的深刻影响得到证实和详细说明。
The most detailed, first-principle simulation model of a quench in a high-temperature superconducting metal-insulation multi-module/multi-double-pancake coil, wound with a REBCO coated superconductor/tape and normal-metal tape (co-wind), was developed. It enables one to simulate a normal zone propagation, or non-propagation, in the subtle multi-turn structure of the coil's pancakes due to the inductive coupling and transverse electric contact between all the REBCO turns and co-wind turns along with the external circuit and active and passive quench protection systems. In doing so, the multi-module coil's structure is represented as a “rectilinear equivalent” electric circuit, a branched multi-decker multi-rectangle planar grid, which facilitates the mathematical formulation, using the standard electric circuit differential equations and the Kirchhoff's rules. The transient non-linear comprehensive heat conduction equations are employed to model the thermal part of the phenomenon at the same level of detail. All this turns the model into an effective design tool for metal-insulated, -stabilized and/or -reinforced multi-module coils. A parametric study of quench in a 6-module no-insulation (NI) test coil, using a stainless-steel thin co-wind, was conducted to identify the possibilities of the model. The profound effect of the transverse contact resistivity on an NI-coil quench behavior is confirmed and detailed.
