风电机组塔架极限风载荷计算及对比研究
|
摘要
以某2 MW水平轴风力发电机组为计算模型,分别采用GH Bladed软件和日本《风力发电设备塔架结构设计指南及解说》对该风电机组塔架的极限风载荷进行计算,并研究在正常发电工况和暴风工况下2种计算方法的差异。结果表明,由2种计算方法得到的正常发电工况下的极限风载荷均大于暴风工况,由GH Bladed软件得到的极限风载荷计算结果偏大。造成极限风载荷差异的主要原因是2种计算方法的风况条件、工况种类及理论基础不同造成的。对于风力发电机塔架这种典型的"高鸡腿哑铃式"高耸结构因其塔顶部位受风轮、机舱的影响较大,采用GH Bladed软件计算结果更精确。
In the 2 MW horizontal axis wind turbine simulation model,using GH Bladed and the Japanese " Guidelines for Design and Explanation of Wind Power Generation Equipment Tower Structure " to calculate the ultimate wind load of the wind turbine tower respectively,and studied the difference in normal power conditions and storm conditions of two kinds of calculation methods. The results showed that the limit wind load in the normal power generation condition is higher than that of the storm condition by the two calculation methods. The results calculated by the Bladed GH are too large. The main reason of the difference of the limit wind load is two kinds of calculation methods,which are the condition of wind condition,the type of working condition and the different theoretical basis. For the wind turbine tower is a kind of typical "high leg dumbbell" high-rise structure,tower parts influence wind wheel,the cabin is relatively large,the calculation results using the GH Bladed software is more accurate.
