摘要
以6 MW海上单柱浮式风力机为研究对象,运用时域耦合分析方法探讨系泊链水平预张力对浮式风力机系统整体运动响应特性的影响。数值研究结果表明:增加系泊链水平预张力能有效改善浮式风力机的纵荡和垂荡运动,对浮式风力机纵摇和横摇运动的影响有限。根据系泊链预张力对浮式风力机整体运动的影响特性优化系泊系统,优化后的浮式风力机具备良好的总体运动响应,该系泊系统能保证浮式风力机的安全。所得结论对浮式风力机系泊系统设计具备一定参考意义。
The influence of mooring chain pretension of wind turbine on motion response characteristics is researched through time domain coupling analysis method,with a 6 MW offshore single column floating wind turbine as the study object.The numerical simulation results show that increasing the mooring chain pretension could effectively improve the surge and heave motion of the wind turbine,while has limited influence on the pitch and roll motion.According to the influence of mooring chain pretension of the wind turbine on motion response characteristics,the mooring system is optimized,which could ensure the safety of the floating wind turbine and enable the floating wind turbine to have a good overall motion response.The conclusions will provide some reference for the design of floating wind turbine mooring system.
