摘　　要：利用自研的Φ-OTDR系统,在福建省某海上风电场开展了演示验证,实现了对海风机机组的启动-运行-停机等不同工况下的状态分析与诊断,总结了不同工况下的振动特征及诊断依据;以及针对海底电缆的水流冲击、锚害拖拽、抵近船只航行等监测预警功能,总结了不同海缆状态下及周边环境感知目标事件特征。实测结果证明该方案能够在线监测海风机与海底电缆状态,并有效感知周围环境,为提升海上风电场运维水平提供了可靠的技术途径。The self-developed Φ-OTDR system was used to demonstrate and verify in an offshore wind farm in Fujian Province. The state analysis and diagnosis of Marine blower unit under different working conditions such as start-up, operation and shutdown were realized, and the vibration characteristics and diagnosis basis under different working conditions were summarized. In addition, according to the monitoring and warning functions of submarine cable, such as current impact, anchor damage towing, sailing of approaching ships, etc., the characteristics of target event perception under different state of submarine cable and surrounding environment were summarized. The measured results showed that the scheme could monitor the status of sea blower and submarine cable online, and effectively perceive the surrounding environment, which could provide a reliable technical way to improve the operation and maintenance level of offshore wind farms.
