| 摘要: |
| 随着我国海上风电的规模化投入运行，风场运维正成为海上风电产业的关注焦点，其中风机海缆故障是面临的主要问题之一。海缆在海洋中受到冲刷影响易发生裸露、悬跨等现象，进一步受 到复杂海洋环境载荷而产生复杂动力响应，导致海缆磨损、疲劳损伤。文章针对广东某风电场风机， 基于绝对节点坐标法与海洋工程水动力学理论建立海上风机接入端海缆的非线性动力学模型，结合 冲刷扫测地形和 CFD 数值模拟得到的桩基绕流区流动特征，在不同海流和波浪工况下对海上风机接入端海缆进行总体响应分析，并进行疲劳损伤评估和磨损评估，为海上风电工程提供运行维护支撑。 |

| Abstract: |
| Driven by the large-scale deployment of offshore wind power in China，the operation and maintenance of offshore wind farms have garnered significant attention，with submarine cable failure emerging as a primary challenge．Due to seabed scouring，power cables are prone to becoming exposed and suspended in the water column． Simultaneously，these cables undergo complex dynamic responses driven by environmental loads，leading to abrasive wear and fatigue damage．In this study，an offshore wind turbine，located in a wind farm in Guangdong Province， is selected as the research case．A non-linear dynamic model of the offshore power cable extending from the offshore wind turbine foundation is constructed based on the absolute nodal coordinate formulation and hydrodynamics．The flow characteristic of the flow area around the foundation is simulated by the Computational Fluid Dynamics considering the scouring seabed．The global response analysis of the power cable extending from the offshore wind turbine is performed in various current and wave conditions．Furthermore，the fatigue damage and abrasive wear are evaluated to provide practical guidance for engineering convenience. |
