Research on reliability analysis of underwater constant current supply system in mesh topology model

The reliability of the remote power supply system is one of the bottlenecks restricting the large-scale and system construction of the cabled underwater information networks. The basic model of the constrained engineering of the constant current remote power supply system is designed. It is assumed that any unit failure in the system is determined as a system fault, and the genetic algorithm-particle swarm optimization algorithm is used to analyze the system power supply reliability of the two-terminal rasterized topology routing scheme. The reliability analysis method is verified through the analysis of calculation examples, confirms the advantages of the underwater constant current power supply system, and the research conclusion can provide a theoretical foundation for research of reliability and design of route program in the cabled underwater information networks.
