摘要： 水下电力载波通信作为水下生产控制系统的主要通信方式之一,其发展水平直接影响油气田开发的安全和成本。脐带缆电力线作为水下电力载波通信的载体,对其特性的分析研究具有至关重要的作用。针对30km脐带缆电力线,利用分布参数集中化方法建立了电力线状态空间模型,并将某深水气田的现场实测rlgc(电阻、电感、电导、电容)参数值代入到系统模型中。根据该模型利用MATLAB软件进一步定量研究了电力线的电气特性,确定了电力线π模型分段数目的选取原则。研究结果对水下电力载波通信系统的信道设计具有一定的参考价值。

Abstract: Subsea power line communication, as one of the main communication methods of subsea control system has a direct influence on the safety and cost of the subsea oil and gas exploitation. Umbilical cable power line is the carrier of subsea power line communication, of which the analysis on characteristics plays a vital role. As for a 30 km umbilical cable power line, state space model is established with the lumped parameter method, and the rlgc (resistance, inductance, conductivity, and capacitance) measured data of a subsea gas field is introduced into the system. The electrical characteristics of power line are researched further using the MATLAB software, and the selection principle of section number for π model is determined. The result of this study has a certain reference value for the channel design of subsea power line communication.
