海上风电基础海底电缆动态特性分析

Dynamic Characteristics Analysis of Submarine Cables for Offshore Wind Power Foundation

基于中国南海实际的海洋环境条件,对冲刷情况下无海缆保护装置及有海缆保护装置的海底电缆分别进行动态特性分析研究,结果表明:在桩周冲刷导致海缆悬空情况下,无海缆保护装置的海缆最小弯曲半径超过允许值,存在失效风险;有海缆保护装置的海缆,海缆保护装置能够有效地限制海缆的过渡弯曲,使海缆的最小弯曲半径控制在允许的范围内,有效降低海缆失效概率。

Based on the marine environmental conditions of South China Sea, the dynamic characteristics of the submarine cable with/without submarine cable protection device under scour conditions are studied respectively, the minimum bending radius of the submarine cable without the submarine cable protection device exceeded the allowable value, and there is a risk of failure. For the submarine cable with the submarine cable protection device, the submarine cable protection device effectively limited the minimum bending radius of the submarine cable, made the minimum bending radius of the submarine cable within allowable range, and effectively reduce the failure probability of submarine cables.
