摘要
海洋石油工程水下通信系统肩负着实时采集水下生产状态信息并将控制信号及时准确送达水下生产系统的重任,水下电力载波通信是当前应用最为经济的方式之一。文章分析了水下电力载波通信系统的架构及特点,基于二端口网络传输矩阵理论,将脐带缆中的电力/信号缆和电力跨接缆抽象为传输矩阵模块,采用Simulation X软件对水下电力载波通信系统线路衰减进行仿真建模,得出0.3~40 k Hz频率范围内,电缆总长、特性参数以及分支数量变化时的线路衰减曲线。线路衰减仿真分析为水下电力载波通信系统的设计提供了重要依据。
Subsea communication system is responsible for collecting production-status information in real time and distributing control signal to the subsea production system reliably in offshore oil project. Subsea power line carrier communication is one of the most economical methods at present. This paper analyzes the architecture and characteristics of the subsea power line carrier communication system. Based on two-port network transmission matrix theory, the electrical/signal cable inside the umbilical and the electrical jumpers are mapped into transmission matrix modules. The line attenuation of the subsea power line carrier communication system is modeled using Simulation X software. Therefore, the line attenuation curves of signal with the change of frequency ranged from 0.3 KHz to 40 KHz, total length, characteristic parameters, and subsea branch numbers are obtained. The line attenuation simulation analysis provides an important basis for designing the subsea power line carrier communication system.
