Simulation Analysis of Power Carrier Communication in Subsea Production Control System

水下生产控制系统作为海上油气田开发生产中重要组成部分,为了分析系统应用中水下电力载波通信衰减情况,建立了基于Multisim软件的水下生产控制系统电力载波通信仿真模型,模型包括传输线路等效电路和采用K式带通结合滤波方式的电力载波发射机、接收机等效模型,仿真分析了在不同频率载波、不同传输距离条件下通讯信号衰减情况;同时分析了两个不同频率的载波信号之间互相的影响,为今后水下生产控制系统项目建设中的供电通信方案设计提供了参考依据。

The subsea production control system is an important part of the development and production of offshore oil and gas fields.In order to analyze the attenuation of the subsea power carrier communication in the system application,a power carrier communication simulation model of the underwater production control system based on Multisim software is established.The model includes transmission circuit equivalent circuit and equivalent models of power carrier transmitter and receiver using K-bandpass combined with filtering methods.Simulation and analysis of the communication signal attenuation under different frequency carriers and different transmission distances;at the same time two different frequencies are analyzed the mutual influence between the carrier signals provided a reference basis for the design of power supply communication schemes in the construction of underwater production control system projects in the future.
