摘要
随着高温超导材料制备技术及低温制冷技术的不断发展,高温超导技术在电机方面展现出良好的应用前景。高温超导发电机由于其体积小、重量轻、效率高的优点,未来有望应用于高功率密度场合。目前对于超导电机故障运行的研究极少,本文对高温超导发电机进行了负载三相断路故障模拟仿真及现场实验,得到故障过程中定子输出电压、转矩等变化的仿真及实验数据,并在此基础上分析了超导线圈的电流变化,及故障对电机机械结构的危害。本文可为超导发电机故障状态的瞬态过程分析提供数据支撑。
With the further development of high temperature superconducting(HTS) material and cryogenic technology, high temperature superconducting technology application has a broad prospect for electrical machines. Because of their advantages, such as small size, light weight and high efficiency, HTS motors are promising for high power density applications in the future. However there is little research focusing on fault condition of HTS motors at present. In this paper the simulations and the field tests of the three-phase load breaking fault condition are studied to obtain the change of the output voltage and the torque of the stator. Based on the results, the superconducting coil current on the magnetic circuit are analyzed, which provides the data support for further study on transient process.
