摘要
针对现有飞轮储能系统中的机械摩擦等问题,提出了无轴承式高温超导飞轮储能装置。储能装置利用高温超导块材料的迈斯纳效应使安装有永磁体的飞轮悬浮,实现无轴承。定子侧安装有三相对称绕组与飞轮构成同步电机结构。利用陀螺仪效应,使飞轮高速旋转,实现储能。利用有限元分析软件,对超导块与永磁体间的作用力进行仿真分析,对在不同尺寸的圆柱永磁体下的悬浮力进行比较。在此基础上,进行飞轮和装置结构设计,并对储能装置储能性能进行了测试,验证了方案的可行性。
In order to solve the problem of mechanical friction in the flywheel energy storage system, a shaftless flywheel en- ergy storage device based on high temperature superconducting (HTS) technology was presented in this paper. Because of the Meisner effect of the high temperature superconducting material, the flywheel with permanent magnet was suspended, which con- tributed to the bearingless of the energy storage device. The stator sidewais provided with a three - phase symmetrical winding and a flywheel, which formed a synchronous motor structure together. Using the gyroscopic effect, the flywheel rotates at high speed to realize energy storage. Finite element analysis software was used to simulate the interaction between the superconducting bulk and the permanent magnet. On this basis, the flywheel and the device structure are designed, and the energy storage performance of the energy storage device was tested, and the feasibility of the scheme was also verified in this paper.
