AI Technical Summary
Existing technologies lack speed and voltage control schemes for DC variable speed generator sets for unmanned ships, resulting in high fuel consumption, long overhaul times, and high noise levels, which hinders the development of civilian or military unmanned ships.
Design a control system for an unmanned surface vessel DC variable speed generator set, including a diesel engine, a rectifier generator, an energy-saving control unit, and an energy management unit. Through variable speed and voltage control, the diesel engine speed and the rectifier generator output voltage can be precisely set. Combined with a seawater pump cooling system, the operating mode of the diesel generator set can be optimized.
This has resulted in lower fuel consumption, shorter overhaul time, and lower noise for unmanned vessels, improved endurance and operational reliability, enhanced stealth and environmental adaptability, and increased power density and installation space utilization efficiency of generator sets.
