【目的】随着海上风电向深远海发展，漂浮式海上风电机组因其具有适应深水环境的优势而成为研究的热点。然而，漂浮式风电机组的动态运动特性加剧了尾流蜿蜒效应，可能影响下游风电机组的发电效率并增加结构载荷，因此需要研究不同风速及机组间距条件下尾流蜿蜒行为的特征。【方法】本研究利用FAST.Farm模拟工具，对5 MW和15 MW半潜型漂浮式风电机组构成的混合阵列进行建模分析。【结果】研究结果表明，尾流蜿蜒现象在低风速时最为显著，其幅度随风速增加而减小。在额定风速以下工况，尾流中心位置的标准差最大，横向为0.24D（D为15 MW风电机组叶轮直径），垂直为0.14D；而在额定风速以 上工况，标准差分别降至0.14D和0.05D。风电机组间距对尾流恢复和发电效率影响显著，间距从2D增至4D时，下游风电机组的尾流亏损降低，发电效率提升。此外，15 MW机组在两边5 MW机组在中间的布局形式相较于15 MW和5 MW交替布局的形式更具优势，将5 MW机组置于第3个机位可降低整体尾流速度亏损，提升第4个机位的来流风速，且15 MW与5 MW机组轮毂高度差异形成的分层尾流结构，在额定风速以上工况中能有效减少15 MW机组尾流对下游5 MW机组的干扰。【结论】本研究系统揭示了尾流蜿蜒效应受风速、间距、布局及风电机组特性等多重因素综合影响的规律，为混合型漂浮式风电场优化设计提 供了理论支撑。

[Objective]With the advancement of offshore wind energy into deep waters, floating offshore wind turbines (FOWTs) have become a research focus due to their adaptability in deep-sea environments. However, the dynamic motion characteristics of FOWTs intensify wake meandering effects, potentially affecting downstream turbine performance and increasing structural loads.Therefore, it is necessary to investigate the patterns of wake meandering behavior under varying wind speeds and turbine spacing conditions.[Methods]This study models and analyzes a mixed array of 5 MW and 15 MW floating turbines to study wake behavior under varying wind speeds and turbine spacings by approaching FAST. Farm simulations. [Results]Results show that wake meandering is most significant at low wind speeds and decreases with increasing wind speed. At below - rated wind speeds, the wake center's standard deviation is highest at 0.24D (D refers to the rotor diameter of 15MW wind turbine) laterally and 0.14D vertically. At above-rated wind speeds, these values drop to 0.14D and 0.05D. Turbine spacing greatly affects wake recovery and power generation efficiency. As spacing increases from 2D to 4D, wake losses downstream decrease and generation efficiency improves. Moreover, the layout with 15 MW turbines at both ends and a 5MW turbine in the middle has advantages over the alternating 15 MW - 5 MW-15 MW-5 MW layout . Placing the 5MW turbine at the third position reduces overall wake speed loss and boosts inflow wind speed at the fourth position. The hub height difference between 15 MW and 5 MW turbines creates a layered wake structure. Above the rated wind speed, this effectively reduces interference from the 15 MW turbine's wake on downstream 5 MW turbines. [Conclusion]The study reveals that wake meandering is influenced by wind speed, spacing, layout, and turbine properties. It offers key theoretical support for optimizing hybrid floating wind farms.
