Research on advanced design technologies of large-scale wind turbine blades for use in complex terrain

Abstract

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.
