Abstract:
The wind energy resource assessment in a complex terrain is very important for the development of wind power generation field. Wind energy resource assessment software WindSim based on the Computational Fluid Dynamics (CFD) method is applied to simulate the wind energy resources of wind farm area in Toksun, Xinjiang in 2007. By comparing simulation results and observation data measured by anemometer towers, it is shown that the software WindSim provides good simulation results of mean wind speed in a complex terrain area, and the mean relative errors of monthly mean wind speed at 10 m, 40 m, 50 m and 70 m are 12.91%, 10.21%, 9.68% and 12.91% respectively. Moreover, the WindSim is able to accurately simulate the predominant wind direction at 40 m and 70 m height. At the same time, the WindSim can also obtain good results of effective wind speed frequency in a complex terrain area. The simulation results of wind energy resources in wind farm show that the area has rich wind energy resources which can be used by wind power generation. It is further indicated that WindSim software can be utilized in the assessment of wind energy resources of complex terrain and has further research value in the future.
