Abstract

The alternating load of aerodynamics, inertial force and elastic force of blade of wind turbine generator system can make elastic vibrator and tower generate coupling vibration to eliminate resonance. The paper takes the blade waving and bend of tower as an example. Firstly, the paper researches irrational tower and rotator wind wheel, and uses modal method to establish the operation equation of rotor hub and engine room tower. Then, the paper uses the deformation consistency condition of rotor hub tower system to couple the operation equation of rotor hub and engine room tower, for establishing complete operation formation of turbine rotor/tower system. Lastly, the paper introduces model coordinate to decouple coupled equations. The response curve the system is achieved. The stability of the system is analyzed, and the factors influencing the inherent frequency of the system is found out.
