摘要

海底电缆的运行状态在复杂海洋环境的影响下增加了随机性和复杂性，现有模型难以量化分析不同影响因素对海底电缆运行状态及停运过程的影响。文中融合不同时间尺度上的海底电缆状态数据，建立海底电缆健康指数计算模型量化评价海底电缆的时变运行状态，在此基础上，考虑外部环境对海底电缆状态的影响，构建海底电缆停运模型表征海底电缆停运行为，展现海底电缆故障发展趋势。最后通过对某海底电缆进行实例分析，验证了模型的可行性和有效性。

Abstract

Under the influence of complex marine environment

the operation status of submarine cable increase randomness and complexity. It's difficult for the existing model to quantify and analyze the influence of different factors on the operation status condition and outage process of submarine cables. In this paper

the status data of submarine cable on different time scales is integrated

a health index calculation model of the sub marine cable is set up to quantitatively evaluate the time-varying operating status of the submarine cable. On this basis

considering the influence of external environmental factors on the status of submarine cable

a submarine cable outage model is set up to characterize the outage behaviour of the submarine cable and show the fault development trend of submarine cable. Finally

the feasibility and effectiveness of the proposed method is verified by real example analysis of certain submarine cable.
