Abstract

Offshore wind farms transmit power via substations, with turbines interconnected to route electricity efficiently to shore-based substations. This study focuses on the safe transmission of power between two Floating Offshore Wind Turbines (FOWTs) using dynamic power cables. The research utilized FOWT models developed through the 12 MW INO WINDMOOR project. In this study, the models' reliability was enhanced by comparing experimental data with simulations conducted using OrcaFlex. Subsequently, four different cable connection methods were investigated and analyzed in terms of tension, curvature, and fatigue. The results indicate that the Lazy wave configuration performs best across all aspects. Although the Suspended and W-configurations exhibit lower rates of tension and curvature increase when transitioning from normal to extreme conditions, their absolute values remain significantly higher compared to the Lazy wave configuration. Additionally, the Catenary configuration may experience axial compression, which requires careful consideration during the design phase.

150m水深下两个fowt阵列间布线方法的数值研究

海上风电场通过变电站传输电力，涡轮机相互连接，有效地将电力输送到岸上的变电站。本研究的重点是两个浮动海上风力发电机（FOWTs）之间的电力安全传输使用动态电力电缆。该研究利用了通过12兆瓦inowindmoor项目开发的FOWT模型。在本研究中，通过将实验数据与使用OrcaFlex进行的模拟数据进行比较，提高了模型的可靠性。随后，对四种不同的电缆连接方法进行了张力、曲率和疲劳的研究和分析。结果表明，Lazy wave配置在所有方面都表现最好。虽然悬挂和w型结构在从正常到极端条件的过渡中表现出较低的张力和曲率增加率，但它们的绝对值仍然明显高于懒波结构。此外，接触网结构可能经历轴向压缩，这需要在设计阶段仔细考虑。
