Abstract:

This paper simulates and analyzes the wind farm in mountainous area under complex terrain in Enshi, Hubei Province by using Meteodyn_WT and based on the analysis results, discuses the wind turbine arrangement and calculates the generaton quantity. Compared with the practical operation over a year, the average measured wind speed of all positions is 6.02 m/s, 0.06 m/s smaller than the calculated results of WT. So the simulated results are satisfied in general. The Meteodyn_WT can reveal the downward trend of wind speed at No. 21 and 22 positions, but the decreasing value can not be simulated. The errors of the simulation results of No.8 to No.11 positions are large, which may be caused by the lack of measured wind speed data of No.2 wind tower. 
