中文摘要：

根据德国GL2010国际标准,运用Bladed软件,对某一850kW的风力机叶片和与之相匹配的风力机发电机组进行建模,并分析其气动额定功率、系统共振等情况,验证叶片运行中的可靠性。分别施加GL标准中的所有工况,对叶片进行仿真计算和比较分析,得到影响叶片气动性能主要是Dlc4.2b、Dlc1.3a等工况,初步建立以叶根载荷为标准的风力机叶片评价体系。此评价体系同样适用于Bladed软件自带的demo叶片模型。以该评价体系为基础,计算850kW叶片叶根处的极限载荷,得到其挥舞极限载荷为353 663N·m,比原设计值小了2.5%,进而验证该叶片在运行中安全可靠,同时,验证了载荷评价体系的可靠性。

英文摘要：

According to the international standard of German GL 2010,a wind turbine of 850 kW is applied to the corresponding wind power generation unit and its situation of pneumatic rated power and sympathetic vibration is analyzed with Bladed software. The result verifies the reliability of wind turbine in operation.Further,after all the wind regimes in GL standard are calculated and analyzed comparatively,the extreme wind regimes which mainly influence the aerodynamic performance of the wind blade are obtained,namely,Dlc4.2b,Dlc1.3a,etc.Later on,the evaluation criteria of wind turbine blade taking the load of blade root as standard are established and implemented with the built-in demo data of Bladed software to testify its generality.Then based on the above evaluation criteria,extreme loads of the850kW＇s blade root is computed and it＇s found the extreme swing load is 353 663N·m,which is 2.5%lower than its designed value.The result verifies the security of the blade in operation and the reliability of the evaluation criteria.
