【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。
[Abstract]:Aiming at the problems of mechanical friction in the existing flywheel energy storage system, a bearingless high temperature superconducting flywheel energy storage device is proposed. The energy storage device makes use of the Meissner effect of high temperature superconducting material to suspend the flywheel with permanent magnet and realizes the bearingless. The stator side is equipped with a three-phase symmetrical winding and a flywheel to form a synchronous motor structure. The gyroscope effect is used to make the flywheel rotate at high speed and realize energy storage. The force between superconducting block and permanent magnet is simulated by using finite element analysis software, and the levitation force under different dimensions of cylinder permanent magnet is compared. On this basis, the flywheel and the structure of the device are designed, and the energy storage performance of the energy storage device is tested to verify the feasibility of the scheme.
