摘　　要：近年来,我国内陆复杂地形条件下风力发电迅速发展,但相关风电机组核心设计技术水平仍然偏低.为此,在中国科学院工程热物理所过去近15年的成果和经验基础上,本文重点围绕对机组效率、可靠性和度电成本起决定性作用的关键部件——风电叶片,开展了复杂地形条件下气动增效、被动耦合降载、轻量化设计等新一代关键技术研究,以构建一体化优化设计技术体系.在填补国内行业空白的同时,力争使我国大型风电叶片的设计水平达到国际先进水平,对解决国家能源安全和环境污染问题具有重要意义.In recent years,wind power has rapidly developed in China’s inland complex terrain.However,the level of core design technologies for related wind turbines is low.Therefore,on the basis of the achievements and experiences of the Institute of Engineering Thermophysics,the Chinese Academy of Sciences for the past 15 years,this study focuses on wind turbine blades,which are essential for the efficiency,reliability,and power cost of the wind power unit.In this study,the new generation of key technologies are researched(e.g.,aerodynamic efficiency increase,passive coupling load reduction,and lightweight optimization under complex terrain conditions)to build an integrated optimization design technology system.This study fills the gaps in the domestic industry and strives to make the design level of large-scale Chinese wind turbine blades achieve the international advanced level.In addition,this study is essential for solving national energy security and environmental pollution problems.
