Offshore wind turbine jacket foundation capable of adjusting inherent frequency and motion damping and control method
The invention discloses an offshore wind turbine jacket foundation capable of adjusting inherent frequency and motion damping and a control method. The offshore wind turbine jacket foundation comprises a jacket, a tuned liquid damper system, a flow monitoring and control system and an acceleration data acquisition and analysis system. The tuned liquid damper system comprises a central liquid bin and distributed liquid bins, the central liquid bin is communicated with seawater, the central liquid bin and the distributed liquid bins conduct liquid conveying through pipelines, and the flow monitoring and control system obtains reserve information of all the liquid bins by collecting data. The acceleration data collecting and analyzing system collects acceleration data at key nodes of a jacket foundation, pumps on all pipelines are controlled based on the obtained data to achieve redistribution adjustment of the liquid storage amount and the liquid level of all liquid bins of the damper system within a short time, the overall mass distribution of the jacket structure is adjusted, and therefore the inherent frequency and the motion damping are adjusted. The offshore wind turbine foundation has the advantages of being convenient to construct and operate and accurate in control, and is suitable for serving as an offshore wind turbine foundation form subjected to long-term dynamic load action.
本发明公开一种可调整固有频率及运动阻尼的海上风机导管架基础及控制方法，包括导管架，调谐液体阻尼器系统，流量监测及控制系统和加速度数据采集分析系统；调谐液体阻尼器系统包括中央液仓及分布式液仓，中央液仓与海水连通，中央液仓与分布式液仓通过管道进行液体输送，流量监测及控制系统通过采集数据获取各液仓储量信息，加速度数据采集分析系统采集导管架基础关键节点处加速度数据，基于所得数据控制各管道上的泵实现对阻尼器系统各液仓的储液量及液位进行短时间内重分布调整，调整导管架结构整体的质量分布从而调整固有频率和运动阻尼。本发明具有便于施工、操作方便，控制精确优点，适合作为遭受长期动荷载作用的远海风机基础形式。
