Simulation and analysis on the levitation force of hybrid HTS flywheel energy storage system

磁悬浮力是块状超导体重要的实用参数,研究磁悬浮力具有实际意义;介绍了超导块材的自稳定悬浮原理;研究了永磁体的半径对系统磁悬浮力的影响,以及在永磁体半径与超导体半径不同时永磁体厚度、永磁体与超导块之间的距离及通过线圈的电流对混合磁悬浮系统的磁悬浮力的影响。使用Ansys软件对混合磁悬浮系统模型进行了仿真分析,并总结了系统各个参数与磁悬浮力之间的关系。最后通过实验验证了所得到的结论。

Levitation force is an important practical parameter of bulk superconductor, and research on levitation force has actual meaning. Stable levitation theory of superconducting bulks was introduced. The impact of radius on levitation force was studied. When the radius of permanent magnet is not equal to the radius of superconductor, the impact of thickness of the permanent magnet, distance between permanent magnet and superconductor blocks and the current through the coil on levitation force of hybrid HTS flywheel energy storage system was researched. Based on Ansys software, hybrid magnetic levitation model was conducted, and the relations of the various parameters of the system were summarized. The experiment was made to verify the obtained conclusion.
