摘　　要：研究了交变磁场对高温超导带材动态电阻的影响。在77 K温度下对高温超导带材动态电阻的各向异性进行了系统性研究,并采用有限元方法建立仿真模型对其进行仿真。结果表明,动态电阻与交变磁场角度和幅值呈正相关。所研究结果对高温超导电力装置降低损耗、提高运行效率具有重要实用价值。In this paper, the effect of AC magnetic field on the dynamic resistance of high-temperature superconducting(HTS) tapes was analyzed.The anisotropy of the dynamic resistance of high-temperature superconducting tapes was systematically studied at 77 K temperature, and a simulation model was established by finite element method to simulate it. The results show that the dynamic resistance is positively correlated with the angle and amplitude of the alternating magnetic field. The research results have important practical value for high-temperature superconducting power devices to reduce losses and improve operational efficiency.
