    Abstract:

    In seismically active regions, more large scale wind turbines are installed. These turbines must consider loads induced by base shaking from an earthquake when calculating extreme loads. The objective of this paper is to study the dynamic characteristics of wind turbine considering wind and seismic loads while the turbine is operating. The 5 MW NREL utility scale reference turbine model is used. Different important scenarios are simulated with various loading conditions. The influence of turbulence intensity and the fatigue loads are analyzed and compared. The results indicate that the maximum of dynamic responses and fatigue loads will increase while the combination of earthquake and operational loads is considered, the mean of dynamic responses will decrease as the increase of turbulence intensity with the baseline control system working. It is concluded that it is significant to compressively analyze the dynamic property for wind turbines constructed in seismically active regions.
