摘　　要：随着海底业务需求的增多,海底光缆网络功能由岸端对岸端的大容量通信链式网络向网格状海底光缆网络发展,作为能源供给和信息传输一体的骨干传输网络。如何满足深海远距离、高可靠能源传输与供给,成为海底光缆网络发展的瓶颈问题。论文分析海底光缆网络的供电拓扑,对水下远程供电网络的电压型和电流型供电架构探讨,通过电路仿真验证海底恒流型供电网络的抗海水短路故障能力和高可靠性。With the increase of submarine application demand,the function of submarine optical cable network has developed from shore to shore high-capacity communication chain network to grid submarine optical cable network,as a backbone transmis⁃sion network integrating energy supply and information transmission.How to meet the long-distance and highly reliable energy trans⁃mission and supply in the deep sea has become the bottleneck of the development of submarine optical cable network.This paper an⁃alyzes the power supply topology of submarine optical cable network,discusses the voltage mode and current mode power supply ar⁃chitecture of underwater remote power supply network,and verifies the resistance of seawater short-circuit fault and high reliability of submarine constant current power supply network through circuit system simulation.
