水下生产系统脐带缆电缆行波传输特性分析及其在故障定位中的应用

Numerical Analysis of Umbilical Cable Traveling Wave Propagation Characteristics and Application in Fault Locaiton

脐带缆电缆故障是影响水下生产系统供电可靠性的关键因素,本文通过对南海某气田水下生产系统脐带缆电缆建立简化等效模型,应用EMTP电磁暂态程序对线路不同情况的故障进行仿真计算分析,得出了脐带缆电缆的行波传播特性,从而为脐带缆电缆故障定位监测装置的参数设置提供有效的参考。

Subsea umbilical cable faults are critical to integrity of subsea production system. A simplified equivalent model was built for the subsea umbilical cable system of a gas field in South China sea. The EMTP（electro-magnetic transient program） is used in the model for simulating calculation analysis of different cable faults and obtaining the traveling wave propagation characteristics, which supports the parameter setting of the subsea umbilical cable fault location equipment.
