本研究开发了多兆瓦级风力涡轮机叶片优化设计与性能分析软件，该软件集风力涡轮机叶片气动外形设计、性能分析、桨距-扭矩分析和叶片形状优化于一体。为了验证软件性能分析结果的准确性，我们选择了5 MW叶片，由NREL设计，作为比较模型，并与著名的商业软件（GH-Bladed）的分析结果进行了比较。GH-Bladed和我们的软件计算的性能分析结果在所有λ范围内的所有CP值都是一致的。此外，为了确认优化设计模块的适用性，使用比较模型的初始设计数据对新的5 MW叶片进行了优化设计，发现在我们的设计中，即使产生相同的输出和效率，坚固性也较小。通过优化叶片设计，效率提高了1%，而推力系数降低了7.5%。
In this research, we developed software for designing the optimum shape of multi-MW wind turbine blades and analyzing the performance, and it features aerodynamic shape design, performance analysis, pitch–torque analysis and shape optimization for wind turbine blades. In order to verify the accuracy of the performance analysis results of the software developed in this research, we chose the 5 MW blade, designed by NREL, as the comparison model and compared with the analysis results of well known commercial software (GH-Bladed). The calculated performance analysis results of GH-Bladed and our software were consistent in all values of CPin all λ ranges. Also, to confirm applicability of the optimum design module, the optimum design of the new 5 MW blade was performed using the initial design data of the comparison model and found that solidity was smaller in our design even though it produced the same output and efficiency. Through optimization of blade design, efficiency increased by 1% while the thrust coefficient decreased by 7.5%.
