Study and Application on Drive Train Torsional Frequency Based on Wind Turbine
In order to accurately analysis and study of wind turbine drive train torsional frequency,considering the factor of the drive train shaft tensional flexibility between a wind turbine and a generator,a wind turbine drive train mathematical model was presented by using equivalent lump mass method in this paper.Then combining with the model analysis method to calculate the two modal frequency of the model,the calculation formula of drive train frequency is received by the actual physical meaning.The result will compare with the simulation of GH Bladed software of drive train model and parameters.The simulation results show that it is validated for the accuracy of the established model of drive train.Taking a wind turbine as an example,it is easy to apply the formula to the actual measurement data and analysis the actual drive train torsional frequency,then guide the model parameter calibration base on the drive train tensional frequency calculation formula.It is better to provide theoretical basis and technical support for the design and application of wind turbine.
