Research on Topological Structure Optimization of Underwater Constant-Current Remote Supply System Based on MMAS Optimization Algorithm

Based on the reliability and construction cost of the submarine cable section, primary and secondary nodes, a topological structure model of a typical chain double-ended constant-current remote supply system is proposed. In the topology model, the underwater unit is equivalent to a series-parallel circuit for simulation analysis. Furthermore, the optimization analysis is carried out from the perspective of system power supply and underwater unit power consumption based on the MMAS optimization algorithm. The results of calculation and simulation shows that the designed model of system has high reliability and has reference significance for the construction of the actual cabled underwater information networks.
