| Abstract: | In order to study the dynamic load variation of the transmission system of wind turbine when aerodynamic coupling acts on it, the paper proposed wind velocity models described with low-frequency and high-frequency wind, then used the method of windower average to cut high-frequency wind and ectract low-frequency one. The effectiveness of the model is proved through the analysis of the characteristics of low-frequency wind and the features of the method. By analyzing the effects on time parameter, it is pointed that this model has good property of time scale. The wind velocity model can be applied effectively in studying dynamic problems related to wind turbine system. |
