Abstract

Considering the time-varying meshing stiffness and meshing phase, flexible shaft and housing, as well as the nonlinear factors of generator such as magnetic saturation characteristics, electromagnetic waves and space harmonics, the rigid-flexible electromechanical coupling dynamics model for the integrated gear-generator system of 8 MW wind turbine is established. The modeling method is verified by experiment. The influence of electromagnetic excitation on the dynamic characteristics of the integrated system is studied. Speed-sweep analysis method, combined with modal vector distribution principle, are proposed to predict the potential resonance speed and search the dangerous components, during the operation process from start-up wind speed to rated wind speed. It is demonstrated that electromagnetic force is the main internal excitation for the integrated gear-generator system, which has a significant influence on the system vibration characteristics. There is a strong coupling effect between the mechanical system and the electrical system. Gear systems are affected by electromagnetic excitation, and the excitation frequency of the gear system also appears in the generator current and electromagnetic torque signal. The system resonance only happens, when the excitation frequency is close to a certain order natural frequency, and the excitation source and main vibration component in this order mode are in the same position as well.
