利用STRM和NCEP数据提高风电场宏观选址的准确性

Improve Accuracy for Macrositing of Wind Farm Based on NCEP and STRM Data

利用STRM数据得出风电场宏观地形,利用NCEP数据提取出风电场的气象数据,在WAsP8.3软件的支持下,计算出描述风资源概况的风速、风功率密度和威布尔分布参数值的分布概况。根据风速、风功率密度分布可以直观地看出风资源的分布情况,根据威布尔分布参数值能够计算出初步的发电量,进而为风电场的宏观选址和下一步测风塔的建立提供依据。

The distribution of wind speed, wind power density and Weibull distribution parameters are calculated which describe wind source based on macroscopic terrain of wind farm from STRM data, meteorological data from NCEP data with software WASP8.3. in this paper. The distribution of wind source can be seen visually by wind speed and wind power density, and elementary power capacity can be calculated by Weibull distribution parameters, it offers the reasons for determination of macrositing location and building wind measuring device in wind farm next.
