Understanding the fault response of superconducting cables is important to their wider adoption. In particular, it is useful to understand how the cable's rating and spatial design would influence both its fault response and time of recovery after a high through fault overcurrent in a particular grid. To achieve that, reliable modelling techniques must be established. A detailed electromagnetic and thermal modelling of a cable will be performed in COMSOL. This modelling will be complemented by a coupled sample power grid model in MATLAB. So far, a successful numerical model of magnetic field dependent behaviour of a Bi-2223 superconducting tape has been demonstrated. This model has been used to propose and verify two homogenization techniques for Bi-2223 tapes that decrease the computation time by simplifying the geometry. Future work will include introducing a thermal model and scaling the problem to cable level.

了解超导电缆的故障响应对其更广泛的采用非常重要。特别是，了解电缆的额定值和空间设计将如何影响其故障响应和特定电网中的高贯通故障过电流后的恢复时间是有用的。为此，必须建立可靠的建模技术。将在COMSOL中对电缆进行详细的电磁和热建模。该模型将由MATLAB中的耦合样本电网模型进行补充。到目前为止，一个成功的数值模型的磁场依赖行为的Bi-2223超导带已被证明。该模型已被用来提出和验证两个均匀化技术的Bi-2223磁带，减少计算时间，通过简化的几何形状。未来的工作将包括引入一个热模型，并将问题扩展到电缆级别。
