摘　　要：随着回接距离增加,水下生产控制系统面临着低压长距离输电的新挑战。根据二端口网络和均匀传输线理论,建立了基于Matlab/Simulink的长距离水下生产复合电液控制系统单相交流和直流电力仿真模型。通过与文昌9-2/9-3/10-3项目电力分析报告和倒推法计算结果对比,验证了本文模型的正确性,弥补了SimulationX水下电力库只能进行单相交流仿真的缺陷。应用本文仿真模型得到了单相交流和直流2种不同供电方式下的建议设计方案,对比了单相交流和直流2种供电方式的优缺点及适用范围。本文所形成的水下生产控制系统电力分析建模方法和设计流程,对我国后续类似工程项目具有一定的借鉴意义。As the tieback distance gets longer, subsea production control system is facing the new challenge of low-voltage power transmission over long distance. Based on the two-port network and uniform trans- mission line theory, a dynamic simulation model for both single-phase AC and DC electricity of subsea elec- tro-hydraulic control systems were developed using Matlab/Simulink. The correctness of the proposed model has been verified by comparing the results of the model with that of existing WC 9-2/9-3/10-3 electrical analysis report and traditional reverse deduction method, thus making up the defect of SimulationX＇s subsea electrical library which can only be used to conduct AC electrical analysis. Schemes for single phase AC and DC power supply have been proposed, and the pros and cons, as well as the scope of application of the two power supply modes have been illustrated. The systematic electrical modeling approach and design procedures for subsea production control systems established herein have essential reference significance for upcoming similar projects.
