摘　　要：远程供电系统的可靠性问题是制约缆系海底观测网络大规模体系建设的瓶颈之一。因此,首先构建了基于恒流供电制式的栅格化远程供电系统可靠性基础模型,按照电流流通路径及各水下单元相互关系,将系统细分为不同的供电链路和链路段;然后,详细分析了各水下单元开路、短路故障状态对系统、供电链路以及观测设备的影响,有针对性地提出了系统基本可靠性、链路可靠性及观测设备供电可靠性的分析方法;最后,通过算例分析,验证了该可靠性分析方法,印证了水下恒流供电制式的优势,提出了水下恒流供电系统可靠性问题分析的建议。该研究结果能够为缆系海底观测网的建设规划与工程设计提供理论支撑。The reliability of the remote power supply system is one of the bottlenecks restricting the large-scale and system construction of the cabled seabed observation network.A basic model of the reliability of a rasterized remote power supply system was constructed based on the constant current power supply system.According to the current flow path and the relationship between the underwater units,the system was subdivided into different power supply links and link segments.The influence of the open circuit and short circuit fault status of each underwater unit on the system,power supply link and observation equipment was analyzed in detail,and the analysis methods of basic system reliability,link reliability and observation equipment power supply reliability were put forward in a targeted manner.The reliability analysis method was verified through the analysis of calculation examples which confirmed the advantages of the underwater constant current power supply system,and suggestions were made for the reliability analysis of the underwater constant current power supply system.The research results are applicable to the construction of the cable submarine observation network,serving as theoretical support for engineering design.
