【摘要】 通过对比传统建筑物与风电机组的特性差异,提出需要考虑风电机组特性的模态振型分析方法及结合风电机组受载特性,修正地震效应的叠加方法。基于此方法对某2.0 MW风电机组进行地震载荷动力学分析,分析数据同风电机组权威软件GH Bladed 4.2数据比较表明,该分析方法可较好地计算风电机组的地震载荷,从而可为简化地震载荷计算流程提供有力技术支撑。更多还原

【Abstract】 This paper compares the differences between tradition building and wind turbine,proposes modal shape approach for wind turbine,and modifies earthquake superimpose means according to loads characteristic of wind turbine.By this means,it processes the system dynamic analysis of seismic effects on a 2.0 MW wind turbine.By comparing with wind authoritative software GH Bladed 4.2,analysis data showed that the method can well calculate the loads of large scale wind turbine in earthquake,which provides a simple and easy-to-use way for earthquake loads calculation.更多还原
