Effect analysis of WRF on wind speed prediction at the coast wind power station of Fujian province

In this paper,in order to obtain the most reasonable parameterization scheme,four different physical parameterization schemes were designed with different boundary,surface layer and land layer in WRF numerical to simulate the hourly wind speed during January 1- 11 July 1- 11,2010,and then the simulation was compared with the observation. The results show that the scheme 2 using MYJ boundary layer scheme,Monin- Obukhov surface layer scheme and Noah land- surface scheme provided the best simulation. According to different wind speed levels,the comparison of wind speeds simulated by scheme 2 with the observation during January and July,2010 shows that,in the case of wind speed 6-15 m /s,the average relative error of simulation amounts to less than 20%,meeting the precision demand of wind power prediction,while for wind speed at 0- 6 m /s,the error goes up because the lack of accurate topographic resolution of model and the special location of the wind tower made the low wind speed easily affected by the land disturbance and the land-sea airflow.
