摘　　要：基于中海油某气田工程项目,对水下生产控制系统采用专用电缆通信和电力载波通信进行仿真对比,基于二端口网络传输矩阵理论,将电缆抽象为传输矩阵模块,模拟仿真得出无论是6mm^2TSQ电缆还是10mm^2TSQ电缆,对于水上主控单元MCS与水下控制模块SCM之间的双向通信信号衰减值来说,专用电缆通信均小于电力载波通信。Having a CNOOC’s gas field project based to simulate and compare the dedicated hard-wire communication with the power-line communication was implemented, including having two-port-network transmission matrix theory based to abstract the cables into the model of transmission matrixes. Simulation results show that, as for 6 mm^2 TSQ cable and 10 mm^2 TSQ cable and the bidirectional signal attenuation between the master control station(MCS) and the subsea control module(SCM) of subsea production control system, the attenuation performance of dedicated hard-wire communication outstrips that of power-line communication.
