摘　　要：为实现10 MW级深水浮式风电平台在高海况环境条下的安全运行,选择多点系泊系统方案,采用时域全耦合动态分析方法,构建10 MW级浮式风电系统一体化分析模型,针对不同风浪流环境条件进行平台运动响应及发电能力评估,建立以限制风电平台运动幅值和系泊缆最大拉力为变量的约束函数,以风电主机最佳发电效能为优化目标函数,计算平台运动响应的变化趋势与风电主机的发电效能,提出优化方程,优化结果分析显示,系泊缆索的数量及预张紧力等参数会显著影响风电主机的发电效率与平台安全性,经过优化后的8点系泊系统可提升浮式风电系统的发电效能与抗风浪能力。The multi-point mooring system scheme was selected for the safe operation of a 10 MW deep-water floating wind power platform under high sea state environment.By adopting the time-domain fully coupled dynamic analysis method,an integrated analysis model of 10 MW-level floating wind power system was established to evaluate the platform motion response and power generation capacity under different environmental conditions of wind and wave.The constraint function was established to limit the motion amplitude of the wind power platform and the maximum pull force of mooring line,and the optimal power generation efficiency of wind power host was taken as the optimization objective function.The change trend of the platform motion response and the power generation efficiency of the wind power host were calculated,and the optimization equation was proposed to obtain the optimization results.The results showed that the number of mooring cables and pre-tensioning force and other parameters will significantly affect the power generation efficiency and platform safety of the wind power host;the optimized 8-point mooring system improves the power generation efficiency and wind wave resistance of the floating wind power system.
