Problems solved by technology

Now some manufacturers are trying to build large-tonnage pure electric ships, but due to the complex research and development technology of the whole ship's power system, and the new design of the whole ship's electrical equipment layout and hull structure, it is basically still in the experimental stage. At this stage, there is no pure electric power system that can be applied to large-scale hulls above 1,000 tons

Embodiment

[0021] This embodiment is a power integration system for a 2,000-ton self-unloading cargo ship propelled by pure electric power with dual-electric, dual-engine, and dual-propulsion, using DC600V DC segment A and B busbars to connect 6 sets of power lithium batteries to each 3 sets of batteries Parallel operation after equal distribution, 6 sets of power lithium batteries can be operated in parallel at the same time, or can be operated independently in pairs of each 3 sets of batteries at the same time by disconnecting the bus contact switch. In case of failure and maintenance, a single set of batteries and any One set of drives operates. At the same time, two sets of power lithium batteries are connected to the DC600V DC segment C bus. In addition to providing power for the power load of the ship's normal navigation, it also serves as a backup power for the power lithium battery. The two groups of power sources as well as between the power source and the power source are indep...

Abstract

A power integration system for a pure electric ship, including a pure electric ship hull, the hull includes multiple sets of energy storage power supply systems, electric propulsion systems, thrusters, inverters and pure sine wave devices installed in the hull cabin; The multi-group energy storage power supply system includes a supercapacitor module and a lithium battery module, which are used to provide power for the entire ship; provide power; the propeller is a straight-wing omnidirectional propeller with rudder and paddle integrated, which is used to propel the ship to sail and control the course; the inverter and pure sine wave device are used to invert and filter direct current into alternating current. In order to obtain the AC380V 50HZ three-phase three-wire and AC220V 50HZ single-phase two-wire power supply for the whole ship; this system has higher integration, driving force and flexibility, which makes it have a wider application prospect in the ship field.

Description

technical field [0001] The invention relates to the field of electric ships, in particular to a power integration system for pure electric ships. Background technique [0002] As a new type of ocean or river transportation, pure electric ships have the advantages of saving energy, being quiet and not polluting water bodies, and will be widely used in the future. The existing electric boats are basically transformed on the existing internal combustion engine hull, and the power mechanism is transformed into an electric or hybrid structure, but most of them use electric motors as auxiliary power, such as using electric drive systems for fine-tuning when berthing. hull. At present, pure electric ship types are concentrated on small ships, such as speedboats. Some manufacturers are now trying to build large-tonnage pure electric ships, but due to the complexity of the integrated R&D technology for the entire ship's power system, and the need for a new design for the entire shi...
