英文摘要： The flywheel energy storage system is one of the effective methods to implement efficient utilization of the energy, and it has become a main research direction of the power battery. In order to effectively conquer the technical problems of the flywheel energy storage system involving high-speed operation of the driving motor, and suspension support of the flywheel rotor, a novel magnetic levitation bearingless induction motor system is proposed in this project. The magnetic levitation bearingless induction motor system, having the advantages of bearingless induction motors and magnetic bearings, can be used for suspension support and energy conversion of flywheel energy storage systems. The magnetic levitation bearingless induction motor system, which consists of two 2 degree of freedom single-winding hybrid-rotor bearingless induction motors and an axial magnetic bearing, incorporates the merits of high power density, high power factor, high reliability, low power consumption, low cost, etc. The aim of this project is to research the fundamental principle and topological structure of the novel magnetic levitation bearingless induction motor system. Thus, the general method of optimization design, performance parameters calculation, mathematical modeling, and simulation analysis will be established. Secondly, the multi-objective coordinated control of suspension, driving, and generation operation of the magnetic levitation bearingless induction motor system under different operating mode will be researched. Thirdly, the fault-tolerant performance of the magnetic levitation bearingless induction motor system will be analyzed, and the general rules of the fault diagnosis and fault-tolerant control will be developed. Finally, the dSPACE-based experiment system will be built, and the corresponding experimental researches will be developed. The successful development of the project will provide the theory and technology foundation for the novel magnetic suspension system. Moreover, it will provide beneficial help for promoting the overall research level of flywheel energy storage systems and the independent innovation capability.
