Abstract: This paper presents the modeling and characteristic analysis of the unknown disturbances for the flywheel energy storage system, considering the property of the three-phase permanent magnet synchronous motor. Firstly, the rotor dynamics mode under the circumstance of the dynamical base is established, and based on this, the model and property of the multi-source disturbances are given in detail. A status detection system is designed and accomplished to gain the essential input parameters for the disturbance. Then, the real-time speed, magnetically bias force and base vibration information can be obtained for the flywheel energy storage system. Finally, the experimental equipment of the magnetically suspended flywheel energy storage system is proposed with the flywheel parameters, which can be used appropriately to demonstrate the disturbance property and its depressing strategy.

Key words: magnetically suspended flywheel energy storage system, permanent magnet synchronous motor, disturbance status detection system
