摘要
该文以大功率风力发电机组为研究对象研究整机系统在地震动力响应的动力学问题。基于Eurocode8随机地震动物理模型生成地震动加速度时程,采用动态入流理论进行气动载荷计算。基于多体系统动力学理论建立风力发电机风轮-塔架结构动力学分析模型,基于此模型对风力发电整机系统进行了地震作用动力学分析。研究表明:地震作用引起的载荷远大于风载作用下的载荷。分析数据同风力发电权威计算软件GH Bladed数据比较表明,该分析模型可以较好的模拟地震作用下风力机的受力情况。
In this paper,the dynamic of a large-scale wind turbine system in earthquake was researched.Based on Eurocode 8,the random ground motion swas generated as acceleration time history,the use of dynamic inflow theory for aerodynamic load calculation.Based on multi-body system dynamics,a wind turbine rotor-tower dynamic model was built,and the system dynamics analysis of seismic effects was researched through the model.The results show that the loads caused by seismic loads are greater than wind loads.The analysis data,compared with the wind power software authority GH Bladed,show that the model can calculate the loads of a large scale wind turbine in earthquake.
