摘要:

水下生产控制系统的正常运行与通信系统的安全可靠息息相关.采用电力载波通信(PLC)方式,引入集中参数这一概念进行建模,并将南海某水下气田的现场实测RLGC(电阻,电感,电导,电容)参数值代入到系统模型中.使用OrCAD Capture软件进行仿真,得到了信号在不同传输路径下的衰减曲线,分析了影响水下电网背景噪声的因素,最后通过限定误码率,计算了任一传输路径在某一频率下所能达到的极限传输速率.研究结果为水下生产控制载波通信系统设计提供了一种参考方法,有一定应用价值.

Abstract:

The normal operation of subsea production control system is closely linked to the safety and reliability of communication system. Power line carrier communication (PLC) model is established with the concept of lumped parameter, and the RLGC measured data of an underwater gas field of the South China Sea is introduced into the system. The OrCAD Capture software is used for simulation. Attenuation curves of different transmission paths are obtained. Finally, through limiting the bit error rate, the attainable transmission rate is calculated. In this way, a new method is provided for the communication design of subsea production system.

Key words: subsea production system, lumped parameter, power line carrier communication, RLGC, OrCAD Capture software
