摘　　要：安装于浅水区域的浮式风力机,需采用配重增强系泊恢复力和平台运动稳定性。为了获取有效的系泊配重设计,文章首先通过AQWA和OpenFAST开发了通用的浮式风力机一体化仿真程序OpenF2A,并基于WindFloat概念进行了重新设计,得到了偏心式平台设计方案;然后计算了风-浪联合作用下5 MW浮式风力机平台运动和系泊张力,定量分析了系泊配重质量的影响。结果表明:在不同风况下,配重对平台运动和系泊张力的影响一致;配重可降低平台纵荡,配重质量越大,纵荡越小;在额定风速下,当配重为65 t时,平台纵荡最大值和平均值分别降低了33.1%和49.1%;配重质量对下风向系泊张力影响较大,可增大系泊张力1倍以上。Floating wind turbines installed in shallow water depths need a clump-weight to enhance the mooring restoring and platform motion stability.In order to obtain an effective mooring clump-weight design,this paper has developed a fully coupled model for dynamic analysis of floating wind turbines based on AQWA and OpenFAST.The public-released WindFloat concept has been improved to obtain a reliable design solution.The platform motions and mooring tensions of the 5 MW floating wind turbine platform due to turbulent wind and irregular wave are predicted.The influence of clump-weight mass is quantitatively analyzed.The results show that the influence of clump-weight on platform motions and mooring loads is independent to wind conditions.The platform surge is reduced by a clump-weight.The surge reduction is larger for a heavier clumpweight.More specifically,the average and maximum values of platform surge are reduced by33.06%and 49.10%for a 65 t clump-weight in the rated wind condition.In addition,the clumpweight has a notable influence on the tension of the downwind moorings.The mooring tension can be doubled due to the presence of a clump-weight.The variation trends of platform motions and mooring tensions under different examined wind conditions versus clump-weight are identical.
