| 摘 要： | 直流海缆是深远海风电送出的核心装备之一，其施工质量对海上风电场的安全运行至关重要。基于悬链线计算模型，提出了直流海缆敷设张力计算方法。利用计算模型，研究了敷设水深、敷设速度及海缆铠装结构及材料对海缆敷设张力的影响规律，并计算了海缆入水角与敷设速度之间的变化关系。基于计算结果所提出的直流海缆敷设张力及弯曲半径控制措施，可指导深远海直流海缆工程建设。

| Abstract: | DC submarine cable is one of the most important equipment of long-distance offshore wind power transmission, and its construction reliability are critical to the safe operation of offshore wind farms. Based on the catenary calculation model, the calculation method for tension of DC submarine cable laying is proposed. Using the calculation model, the influence of laying depth, laying speed, submarine cable armor structure and materials on the tension of submarine cable laying is studied. The variation law between the angle of submarine cable entry and laying speed is also calculated. Based on the calculation results, the proposed control measures for the tension of DC submarine cable laying and bending radius can guide the construction of long-distance offshore DC submarine cable project. |
