近两年我国电力突然短缺,已经引起政府的高度重视.由于我国风电发展的紧迫性和风电发展的潜力,特别是国际上正在如火如荼地开发风电的情景,中国-奥地利政府间双边合作计划将风电评估列入2001～2003年度合作计划,论文是该计划的成果之一.以我国吉林省为研究对象,采用广泛使用的风机选址算法和空间分布诊断程序(WAsP和ZAWIMOD2),运用数字地形图和遥感资料获得的土地利用图,进而得到数字化的表面粗糙度,再对吉林省的风能潜力进行估算.完成了近1km2分辨率的距地面60m高度的风速和风能密度计算,并制作了它们的分布图.这是我国第一次在较大区域上估算距地面60m高度的风速和风能密度,其方法对我国风电资源的评估有重要的借鉴作用.结果显示最有效的风能资源在吉林省的中西部地区,而南部和东部的高风资源区位于山脊和山顶,对风能的开发有一定的限制.

The wind energy potentials of the Jilin Province,China,is estimated by means of certain algorithms and procedures for wind turbine siting,digital terrain maps and digitalisation of surface roughness on the basis of certain land use maps. For the necessary meteorological input data only such were used easily available from the ordinary meteorological network. On a grid of nearly 1km × 1km the mean annual wind speed and the wind power density 60 m above ground level were mapped. Generally,the most favourable wind resources are found in the central and western part of the province. High wind resource areas in the southern and eastern part are located on ridges or crests and mountain summits.
