开发了一个数值分析程序，模拟了短路电流事故下过冷液氮冷却的高温超导电力电缆内的瞬态温度和压力分布。该计算机模拟程序不仅包括HTS电力电缆本身的温度和压力分布的计算，而且还包括冷却系统（包括循环泵）的温度和压力分布的计算。2015年，住友电气工业展示了一种66 kV 40 m模型电缆，并进行了故障电流测试，在测试过程中，铜线圈架的铜导体之间的空隙被绝缘材料填充。在这项研究中，模拟模型电缆进行了考虑到液氮不吸收的铜线圈架。通过考虑进口处液氮温度的升高和介电层热导率的瞬态值，发现该模拟更精确地匹配实验数据。
A numerical analysis program has been developed to simulate the transient temperature and pressure distribution in an high-temperature superconducting (HTS) power cable cooled by a forced flow of subcooled LN2 during a short-circuit current accident. This computer simulation program includes computations of temperature and pressure profiles not only in the HTS power cable itself, but also in the cooling system, including the circulation pump. In 2015, Sumitomo Electric Industries demonstrated a 66 kV 40 m model cable with a fault current test, during which the void between the copper conductors of the copper former was filled by insulation material. In this study, simulations of the model cable were performed by considering that LN2 is not absorbed in the copper former. This simulation was found to more precisely match experimental data by considering the rise in LN2 temperature at the inlet and transient value of the thermal conductivity of the dielectric layer.
