摘要全球化石能源的短缺及气候变化,推动了风力发电的飞速发展。风能资源状况的评估与统计是风电场项目综合评估的根本,是决定风电场建设取得良好效益的关键。本文在回顾了近10年来的风能资源评估技术方法发展历程的基础上,分析比较了所研究的风资源评估方法的特点[1]。从研究风资源和风特性着手,讨论了风剪切、湍流、尾流等对风电机组载荷及疲劳的影响,研究了计算流体力学(CFD)的应用对风能资源评估技术特别是在复杂地形方面的发展所起的重要作用[2]。使用专业的风数据处理软件windographer处理测风数据以向CFD提供输入数据,通过对某风电场风资源的全面评估总结了风资源评估及风电场选址的关键影响因素。本文的结论对风电场的选址及机型的选择有一定的指导意义。30979 关键词 风能 计算流体力学(CFD) windographer 资源评估 测风数据分析 毕业论文设计说明书外文摘要 Title The analysis method research based on the wind data of Windographer Abstract The shortage of fossil fuels and global climate change promote the rapid development of wind power. The condition of wind energy resources assessment and statistics are the root of the wind farm project comprehensive evaluation and the key to achieve good benefit of wind farm construction. By reviewing the recent ten years development of wind energy resource assessment methods, this paper analysis and compares research of the characteristics of the wind resource assessment method . Start from studying the characteristics of wind resources and wind, then discusses the wind shear, turbulence, wake effects on wind turbine load and fatigue.This paper studies the application of computational fluid dynamics (CFD) that play an important role of the wind energy resource assessment especially the development of technology in complex terrain .Using professional wind data processing software such as windographer to solve wind data to provide input data for CFD, points out the key influence factors on the wind resource assessment and the site selection of wind farm, provides an important guiding significance for the selection of wind farm site and turbine model.
