摘　　要：针对漂浮式风机系泊张力解算中多源误差影响问题,以广东徐闻海域"扶摇号"半潜式风机为研究对象,基于Orcaflex建立风-浪-流耦合数值模型,对准静态悬链线方程解算方法的误差源开展量化分析。研究表明:导缆孔竖向位置变化在25m纵荡位移时会导致12%的张力误差,系泊倾角±0.5°测量误差在低倾角工况下将产生8.7%的张力偏差;而悬链线面外运动、监测点位置偏移±1m对解算精度影响较小。动态仿真表明,准静态模型能较好捕捉迎浪侧系泊张力时域趋势,但背浪侧因平台倾斜导致均值偏差。研究建议在浅水海域需重点关注导缆孔高度变化及安装精度的影响,并通过神经网络模型融合多源监测数据以提升解算精度。To address the multi-source error effects in mooring tension prediction for floating offshore wind turbines,this study establishes a coupled wind-wave-current numerical model using Orcaflex,focusing on the"Fuyao"wind turbine platform in Xuwen,Guangdong.A quantitative analysis of error sources in the quasi-static catenary equation method is conducted.Results reveal that vertical fair-lead displacement of 25 m induces 12%tension error,while±0.5°mooring angle measurement deviations under low-angle conditions cause 8.7%tension discrepancies.Out-of-plane motion and±1 m monitoring point shifts exhibit minor impacts.Dynamic simulations indicate that the quasi-static model effectively captures time-domain trends of windward mooring tension but shows mean deviations on the leeward side due to platform tilt.The study recommends prioritizing fair-lead height monitoring in shallow waters and integrating multi-source data via neural networks to enhance calculation accuracy.
