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。
In the past two years, the sudden shortage of electricity in our country has drawn great attention from the government. Due to the urgency of wind power development in our country and the potential of wind power development, especially in the international arena in full swing to develop wind power situation, the China-Austria Bilateral Cooperation Plan includes wind power assessment in 2001-2003 annual cooperation plan. One of the results. Taking Jilin Province of China as the research object, the widely used wind turbine site selection algorithm and spatial distribution diagnostic program (WAsP and ZAWIMOD2) are used to obtain the digitalized surface roughness by using digital topographic maps and land use maps obtained from remote sensing data. Wind power in Jilin Province is estimated. Wind speed and wind energy density calculations at a height of 60 m above the ground with a resolution of nearly 1 km 2 were completed and their distributions were made. This is the first time for China to estimate the wind speed and wind energy density at a height of 60m above the ground in a large area. The method has an important reference for the assessment of wind power resources in China. The results show that the most effective wind energy resources are in the central and western regions of Jilin Province, while the high wind resource regions in the south and east are located on ridges and summits, which restrict wind energy development.
