Problems solved by technology

[0003] However, the vibration and noise of ships propelled by diesel engines are large, which reduces the comfort of the crew and passengers, and once the important parts of the main engine or the steering gear and shafting fail, the ship will often be paralyzed
The mechanical propulsion system has a transmission shaft system and a reduction gearbox, which is not convenient for the layout of the engine room

Abstract

The invention discloses a marine electric propulsion system. The marine electric propulsion system comprises multiple parallel diesel generating sets, an electric energy management system, a rectification inverter and an electric motor, wherein each diesel generating set comprises a diesel engine and an electric generator, and the diesel generating set drives the electric generator to generate electricity; the electric energy management system is used for controlling the power output of each diesel generating set and realizing the full-automatic parallel operation of each diesel generating set; the rectification inverter is connected with the diesel generating set; and the electric motor is a variable frequency electric motor, is connected with the rectification inverter and is used for driving a propeller. The marine electric propulsion system adopts the electric motor to replace a heat engine for directly driving the propeller, the operation number of parallel units can be selected according to electrical loads, and therefore, the units always operate in an efficient working area to realize maximum economic efficiency.

Description

technical field [0001] The invention relates to the field of engines, in particular to a marine electric propulsion system. Background technique [0002] During the ship's navigation, the ship's power system is the most important technical part of the ship. At present, the most commonly used propeller propulsion device is the mechanical propulsion system. The mechanical propulsion system is composed of a heat engine, shafting, shafting accessories, transmission equipment and propellers. The propellers are directly driven by heat engines (diesel engines, steam turbines and gas turbines, etc.). [0003] However, the vibration and noise of ships propelled by diesel engines are large, which reduces the comfort of the crew and passengers, and once the important parts of the main engine or the steering gear and shafting fail, the ship will often be paralyzed. The mechanical propulsion system has a transmission shaft system and a reduction gearbox, which is not convenient for the ...
