Abstract

The invention discloses a control method of a DC networked ship hybrid propulsion system capable of automatically switching propulsion modes according to the operating environment. During the voyage, the ship hybrid propulsion system based on DC networking of the present invention monitors the sea area environment where the ship is located in real time through navigation radar and marine GPS, obtains its location, and at the same time judges the propulsion mode required by the ship in conjunction with the navigation route, and Control related equipment to automatically switch modes, the entire monitoring and switching process does not require human intervention, avoiding losses caused by operator negligence, and improving the operational safety of the ship and the degree of intelligence of the ship.

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...
