Research and Application of Turbulence Intensity Calculation Based on CFD in the Wind Farm

摘要：

　　The turbulence intensity is not only an important parameter in wind energy resource assessment,but also is the main basis of WTGS design and equipment shaping.This paper introduces the methods of turbulence intensity calculation,especially the method based on turbulence transport models in CFD.The CFD method of Meteodyn WT is applied to calculate turbulence intensity of wind farm site in complex terrain of some area,and the simulation results is compared with measured date by mast and the simulation results based on the line model.The results show that CFD method of Meteodyn WT provides good simulation results of turbulence intensity.It is significant that the CFD method is applied in wind resource assessment and micrositing of wind farm.
