Passive damping systems have been widely studied to improve the response of wind turbine structures under operational conditions. However, there is insufficient information on how these systems enhance reliability for extreme loads. Wind farm construction has been growing rapidly in recent decades, thereby moving wind turbine structures to sites with higher seismic and hurricane hazards. This research presents a numerical study performed on three land-based wind turbines, similar to typical turbines installed in Mexican wind farms, under cyclone-induced wind and earthquake action. The fictional location of the turbines is justified by the wind capacity distribution of Mexico, which is a country with high seismic and tropical cyclone risk. The wind field is simulated from semiempirical mean velocity models, and the ground motion records are obtained from real events recorded near the assumed site. All the time history analyses assume that the turbines are in parked condition. The results indicate that a fragility reduction of approximately 80% can be achieved under cyclone-induced winds when passive damping systems are added to the structure, and that the fragility reduction is significantly less under seismic action.

旋风和地震载荷下带调谐质量阻尼器的陆基风力涡轮机脆性曲线的发展

被动阻尼系统已被广泛研究以改善风力涡轮机结构在运行条件下的响应。然而，关于这些系统如何提高极端负载可靠性的信息不足。近几十年来，风电场建设发展迅速，因此将风力涡轮机结构转移到地震和飓风灾害较高的地点。本研究介绍了对三个陆基风力涡轮机进行的数值研究，类似于安装在墨西哥风电场中的典型涡轮机，在旋风引起的风和地震作用下。涡轮机的虚构位置由墨西哥的风容量分布证明是合理的，墨西哥是一个地震和热带气旋风险高的国家。风场由半经验平均速度模型模拟，并且地震动记录是从假设站点附近记录的真实事件中获得的。所有的时间历程分析都假设涡轮机处于停放状态。结果表明，当被动阻尼系统添加到结构中时，在旋风引起的风下可以实现大约 80% 的脆性降低，并且在地震作用下脆性降低显着减少。
