| 摘 要： | 根据坐标转换及力学分析,推导风电机组叶根坐标系和风轮坐标系之间的载荷传递关系,建立更接近实际工况的载荷分析模型。文章以某5 MW风电机组为分析对象,对新分析模型、简化模型和GH Bladed模型进行结果对比,验证该分析模型具有更高的可靠性和精确性;根据机组载荷组成,通过获取坐标转化过程中各组成因素的实例数据,对各组成因素的影响程度进行精确分析,对控制及降低载荷具有重要意义。

| Abstract: | Based on coordinate transformation and mechanical analysis, load transformation between blade root and rotor coordinate system for wind turbine is derived.And an analysis model closer to actual working condition is established.Taking a 5 MW wind turbine as analysis object, analyzing results of the new model, traditional simplified model and GH Bladed model are compared, and results are good enough to validate this new model has higher reliability and accuracy.In addition, based on analyzing to load component, through access to instance data of each factor in process of coordinate transformation, the impact of each factor can be accurately analyzed, which is of great significance to control and reduce load. |
