Product Introduction
DC networking technology is an innovative networking technology that uses DC to connect electromechanical equipment. It is a major upgrade and optimization of AC networking technology and is considered by the industry as a new generation of electric propulsion system solutions.
The main features and advantages are as follows:
1. Innovative topology of DC networking electric propulsion system
The DC network power propulsion system splits the AC-DC-AC conversion link in the AC inverter, and transfers the networking side of all equipment from the original generator AC side to the DC side, but its power generation equipment and load equipment still use AC mode, which solves the problems of generator grid connection, harmonic suppression and system resonance.
2. Higher equipment integration
Due to the use of DC networking and asynchronous generators, transformers, switchboards and other equipment are saved, the volume of system equipment is saved by about 30%, and the weight is saved by about 40%. While saving equipment, a large number of equipment interfaces and wiring cables are omitted, reducing system costs.
3, lower fuel consumption and noise
Support the variable speed diesel engine scheme, so that the diesel engine runs at a reduced speed under low load, the diesel engine runs in a high-efficiency area, and the fuel saving rate reaches 10% ~ 20%; At the same time, the diesel engine runs in the noise optimization area when the speed is reduced, and the noise can be reduced by 30%.
Applicable ship type and characteristics
Typical ship types include:
Scientific research ship: comprehensive survey ship, marine hydrographic survey ship, survey ship, geological survey ship
The operating conditions are complex and changeable, carrying a large number of scientific research equipment and instruments, sensitive to the hull space, and relatively sensitive to the noise during operation measurement.
Special vessels: official vessels, fishery administration vessels, maritime surveillance vessels, underwater vessels
The operating conditions are complex and changeable. Special ships, especially underwater ships, have extremely harsh requirements for hull space and are extremely sensitive to noise.
Offshore engineering ship: platform supply ship, platform engineering ship, three-use work ship, wind power installation ship.
The operating conditions are complex and changeable, the fuel-saving potential is huge, the hull space is relatively compact, the space occupied by the equipment is sensitive, the use of a large number of frequency conversion deck machinery, and the DC network electric propulsion system connection is simple and convenient.
Cruise ships: luxury cruise ships, sightseeing ships, tour performing arts ships, etc;
The power load of the power system of the cruise ship varies greatly under different operating conditions of full-speed sailing and cruise, which is sensitive to the equipment space requirements.
