Abstract

The invention discloses a control method of a direct-current networking ship hybrid power propulsion system capable of automatically switching propulsion modes according to an operation environment. According to the ship hybrid power propulsion system based on direct current networking, in the navigation process, the sea area environment where a ship is located is monitored in real time through the navigation radar and the marine GPS, the position where the ship is located is obtained, meanwhile, the propulsion mode needed by the ship is judged in combination with the navigation route, and related equipment is controlled to automatically conduct mode switching; the whole monitoring and switching process does not need human intervention, loss caused by negligence of operators is avoided, and the operation safety and the intelligent degree of the ship are improved.

Description

technical field [0001] The invention relates to a ship hybrid propulsion system, in particular to a control method for a ship hybrid propulsion system in a DC network. Background technique [0002] In recent years, with the emphasis on the marine environment and the in-depth advancement of the global marine strategy, emission regulations have become increasingly stringent, and how to promote energy conservation and emission reduction of ships is imminent. Saving ship navigation costs, reducing ship emissions and reducing its dependence on non-renewable energy have always been important research hotspots in ship development. With the development of hybrid power technology, a marine hybrid propulsion system has emerged, which can not only reduce the total fuel consumption and emissions of ships, but also reduce the environmental pollution caused by ships, thereby obtaining dual benefits of economy and environmental protection. [0003] A ship hybrid propulsion system refers t...
