摘　　要：为解决漂浮式风力发电机在中浅水海域中系泊系统的设计问题,采用全耦合时域方法对不同锚链长度、锚链形式的系泊系统开展动态响应数值模拟。通过开展不同系泊缆长度对平台控制效果分析、新型锚链在额定风速工况下的轴向力、功率谱密度及垂荡运动响应分析、多因素下张紧式锚链的运动响应等研究,对浮式风机系泊设计进行系统评估。研究结果表明,浮体和配重块对改变系泊缆的形状可起到有效作用;相对于悬链线式锚链,张紧式系泊缆对漂浮式风力发电机的垂直、纵摇、纵荡的总体控制效果更有效;在锚点固定和锚链的许用强度范围内,垂向角与平台控制效果成反比,预张力与平台控制效果成正比。In order to solve the design problem of mooring systems for offshore floating wind turbines in shallow and medium waters,the mooring systems with different cable lengths and cable forms were simulated to study their dynamic responses under different sea conditions by using the fully coupled time-domain method.The effects of different mooring rope lengths on platform control,as well as the axial force,power spectral density and heave motion response of the new anchor chain under rated wind speed conditions,were analyzed.In addition,the motion response of the tensioned anchor chain under the influence of multiple parameter factors was also studied to comprehensively evaluate the mooring design of floating wind turbines.The results indicated that the floating body and counterweight play an effective role in changing the shape of the mooring ropes;in addition,compared to catenary anchor chains,tensioned mooring ropes have better overall control effects on floating wind turbines in terms of vertical,pitch,and surge.When the anchor point is fixed and within the allowable strength range of the anchor chain,the platform control effect is inversely proportional to the vertical angle and directly proportional to the pre-tension.
