As the worlds first floating wind farm, one of the main technical challenges in the design phase of Hywind Scotland was the uncertainty related to wake interaction effects between the floating wind turbines. In this paper, we address this challenge by presenting an analysis of full‐scale measurements from the Hywind Scotland wind farm. Measurements of the floaters' roll, pitch and yaw motions are presented, both in the form of statistical data and response spectra. The floater responses of a turbine in free wind and a turbine in wake are compared, and the influence of different atmospheric stabilities on the floater motions is investigated. Despite the large distance between the turbines of 9 rotor diameters, wake effects in the measured floater motions are observed at the downstream turbine. Furthermore, both the wake responses and the free wind responses show a clear dependency on atmospheric stability. However, overall motions are small for all wind speeds, showing that the design performs satisfactorily in both free wind and wake conditions.

尾流和大气稳定性对Hywind Scotland风力涡轮机浮子响应的影响

作为世界上第一个浮动风力发电场，Hywind Scotland设计阶段的主要技术挑战之一是与浮动风力涡轮机之间的尾流相互作用影响相关的不确定性。在本文中，我们通过对苏格兰Hywind风力发电场的全面测量结果进行分析来应对这一挑战。以统计数据和响应谱的形式给出了对漂浮物的滚动，俯仰和偏航运动的测量。比较了自由风轮机和尾流轮机的浮子响应，并研究了不同的大气稳定性对浮子运动的影响。尽管具有9个转子直径的涡轮之间的距离较大，但在下游涡轮上观察到了在测量的浮子运动中的尾流效应。此外，尾流响应和自由风响应都显示出对大气稳定性的明显依赖性。但是，对于所有风速而言，整体运动都很小，这表明该设计在自由风和尾风条件下的性能均令人满意。
