针对中国部分近海海上风电场位于高烈度地震区而面临地震潜在威胁的问题,提出地震风浪作用下导管架基础海上风力机结构整体耦合分析方法,开发地震荷载计算模块,基于FAST v8建立海上风力机地震整体耦合分析模型。根据整体耦合模型,揭示了地震风浪作用下海上风力机运动响应特性以及机电安全控制策略在减振方面存在的不足。进一步提出机电安全控制-MTMD联合减振控制策略,并探讨叶片顺桨速率对联合控制策略减振效果的影响;同时,以海上风力机结构地震响应为评价指标,对该联合控制策略的有效性进行了验证。
Abstract
Due to the fact that some offshore wind farms in China are located in high intensity earthquake regions, they are facing the potential threat of earthquakes. Hence, the seismic module is developed and added to the simulation tool FAST v8 based on the derived fully coupled analysis method for offshore wind turbines （OWTs） under earthquakes, in order to establish the fully coupled seismic analysis model of OWTs. Based on the coupled seismic analysis model, the dynamic characteristics of OWT under earthquake, wind and wave loads are introduced, and the limitations of the mechanical control strategies on the reductions of seismic responses are proved. Then, the joint mechanical and multiple tuned mass damper （MTMD） vibration control strategy is suggested, and the influence of feather rate on the mitigation effects is investigated. Further, the applicability and effectiveness of the joint mechanical-MTMD control strategy is validated based on the reductions of OWT seismic responses.
