用于海底观测网络的海缆远程供电系统的可靠性

Reliability research of submarine cable remote power supply system of seafloor observatory network

提出了串联恒流和并联恒压两种适合应用于海底观测网络的远程供电系统方案;在相同条件下,利用算法分别完成了两种系统的可靠性设计与分配方案,并根据各子单元的分配可靠度计算了两种系统各节点的供电可靠度。分析结果表明:相比于并联恒压远供系统,串联恒流远供系统对子单元的要求相对较低,而各节点的供电可靠度相对较高,说明串联恒流远供系统更适合应用于我国的海底观测网络建设。

This paper makes a deep analysis of the parallel-constant-voltage and series-constant-current remote power supply system which is used in the deep seafloor observatory network. The reliability design and allocation schemes are accomplished to minimize the total cost of the system in the same condition. The power feeding reliability of individual knots in the two systems is calculated. The comparative analysis result shows that the series-constant-current system is more adaptable to the seafloor observatory network of our country.
