摘要

为了了解高温超导磁体的热行为,提高高温超导磁体在电力系统模拟动态实验中的热稳定性,我们进行了热分析。本文采用基于热传导方程的模型,对过流状态下的热分析和恢复特性进行了分析,并采用有限元方法进行了求解。磁体由制冷机通过冷却板冷却。本文主要研究了磁体内部的温度分布以及磁体与冷却板之间的传热。在此基础上,讨论了高温超导磁体的热稳定性问题。

Thermal analysis of the HTS magnet for simulated dynamic experiment of electric power systems in over-current state
We perform thermal analysis in order to understand the thermal behavior of the HTS magnet and improve the thermal stability of the HTS magnet for simulated dynamic experiment of electric power systems. In this paper, the thermal analysis and recovery characteristics in over-current state are analyzed by using the model based on the heat conduction equation and solved using the finite element methods. The magnet was cooled by a cryocooler through a cooling plate. This study focused on the temperature profile in the magnet and the heat transfer between the magnet and the cooling plate. Based on the results, the issues related to thermal stability of the HTS magnet are discussed.
