利用山东省沿海测风塔70 m 高度完整1a的观测资料计算分析风能资源参数特征。结果表明:山东沿海地区平均风速与有效风功率密度分布特征相似,烟台沿海区域平均风速及有效风功率密度最大分别达到6?7 m/s、463?5 W/m2,沿海北部地区风能资源最为丰富,日照地区最少;受海陆风作用,春季风能资源最好,其次是冬季,夏季最差,风速最大值基本出现在14-16时;年有效风能时数及百分率分别为7440 h、85%;风能密度分布基本以偏北或偏南方位较大。沿海区域风能资源分布特征与长年代评估结果及数值模拟结果基本一致。

Based on observational data at 70 m height from 19 wind towers from Jun 1,2009 to May 31,2010 in Shandong coastal areas,the reserves and distribution characteristics of wind speed and wind energy at 70 m height were analyzed using statistical methods. The results show that the distribution characteristics of the average wind speed are accordant with effective wind power density in Shandong coastal areas.The average wind speed and effec-tive wind power density are up to 6?7 m/s and 463?5 W/m2,respectively in Yantai coastal area.The wind energy resources are much richer in the north area than in other areas,with the poorest being in Rizhao area.Due to the in-fluence of sea breeze,the wind energy resources are richest in spring,followed by winter,and poorest in summer, and the maximum of the daily wind speed appears in period of 14:00-16:00.Results also show that the mean an-nual effective hours of wind and its percentage are 7 440 h and 85%,respectively. The distribution of wind energy density is larger in the northerly or southerly azimuth.The distribution characteristics of wind speed and wind energy are generally consistent with the results of long time evaluation and numerical simulation.
