Abstract
- To improve the utilization of wind energy, a new type of deflectable double-stators switched reluctance wind power generator is proposed to solve the unicity of the rotor rotation of existing switched reluctance generator (SRG). The generator adopts inner and outer double-stators structure. The multi-degree-of-freedom deflection of the rotating shaft can adapt to different wind directions and is suitable for the combination of electric fields with unstable energy amplitude, which can improve the working efficiency of the generator. The finite element analysis is used to calculate the rotation of the air gap magnetic flux inside the generator rotor, which lays a foundation for analyzing the vibration displacement of the stator structure. The magnetostriction of stator structure is the main cause of generator vibration. Based on the theory of mechanics, the basic equation of structural mechanics considering magnetostrictive effect is established. Magnetio-solid coupling simulation of internal and external stator and rotor rotation and deflection is carried out using FEA, and the stress distribution and corresponding vibration displacement are obtained. The simulation and analysis results provide a reference for further optimizing the structure of such generators and improving the stability of their operation. [ABSTRACT FROM AUTHOR]
