摘要

以某海峡铺设的110kV XLPE（交联聚乙烯）光电复合海底电缆的故障类型检测为目标

提出了一种利用海缆中复合的光纤检测其故障类型的方法。该方法首先使用IEC标准、PSCAD（电力系统计算机辅助设计）软件和ANSYS有限元仿真软件对不同故障时海缆温度进行计算及仿真;然后在不同故障情况下从这类海缆的温度数据中提取出光纤温度数据

分析不同故障时光纤温度变化情况

推导出光纤温度变化与海缆故障类型的关系;最后分析故障点位置不同对光纤温度变化的影响。分析结果表明

该方法可以成功检测出海缆故障类型

对海缆的故障检测具有重要参考价值。

Abstract

In order to detect the fault types of 110kV XLPE photoelectric composite submarine cable across a certain strait

a diagnosis method of using the fibers in the cable is proposed.In this method

the IEC standard

Power Systems Computer Aided Design（PSCAD）software and ANSYS software are first used for the calculation and simulation of the temperature of the submarine cable in different faulty conditions.Then

the fiber temperature data are extracted from this cable temperature data

the fiber temperature changes in different faulty conditions analyzed and the relationship between the fiber temperature changes and the cable fault types derived.Finally

the effects of the fault position on the fiber temperature changes are analyzed.The analytical results show that this method can successfully detect the fault types of submarine cables and has significant reference values for their fault detection.
