山东即墨风电场风力资源分析

Analysis of Wind Resources at Jimo Wind Farm in Shandong Province

以即墨气象站风速风向为参考，利用其30年风速资料确定风电场代表年，根据铁塔气象观测资料分析即墨风电场的风力资源状况；依据“风能资源评价技术规定”对即墨风电场的风速风向进行了检验修正。分析了测风塔各高度风速日、年变化，风向频率年月变化。计算分析了测风塔不同高度平均风速、风功率密度、有效小时数等风能参数。计算了不同风电机型60-70m轮毂高度年发电量及其随高度变化规律；估算了风电场年发电量。得出即墨风电场达到3级风场标准，具有开发价值。

The wind resources of the Jimo wind farm are analyzed and the representative years are determined by means of the 30-year wind data from Jimo Weather Station and the wind measurements from a meteorological observation tower. Tests and emendation are conducted according to the related technical stipulations. Analyses and computation are made of the wind energy parameters measured at the tower such as the daily and annual variation of wind speed, the monthly and annual variation of wind direction frequencies, the mean wind and wind power density, effective hours of wind speed, etc., as well as the power output and its variation regularities with height for various wind turbines. It is concluded that it is worthy of development only when the winds reach Grade 3 on the Beaufort scale for a wind farm.
