Detailed description of the invention
Below with reference to accompanying drawing, give the specific descriptions of optional embodiment of the present utility model.
It is half latent cargo ship electric power and the one of propulsion system that hybrid propulsion combines direct current network
New solution.
Specifically, as it is shown in figure 1, this system includes sustainer 11 and 21 (bag
Include but be not limited to diesel engine, natural gas engine or double fuel machine), change speed gear box 12 and
22, propeller 13 and 23 (including but not limited to controllable pitch propeller), axle translator 14 and
24 (electric generator/electric motors), current transformer 15 and 25, assisted engine 31 and 41, master
Electromotor 32 and 42 and current transformer 33 and 43.Through current transformer 15 and 25 and become
The unidirectional current that stream device 33 and 43 generates various loads 10 on supply vessel.General feelings
Under condition sustainer 11 and 21 and the axle translator of correspondence be installed on stern, main generator
32 and 42 are installed on bow.Owing to semi-submerged ship head and the tail are big for distribution span, this layout
It is easy to some operating mode realize powering nearby, thus reduces loss.
The operation principle of this system is as follows: it use sustainer 11 and 21 as promote mainly into
Equipment, axle translator 14 and 24 is as auxiliary propulsion equipment.By electromotor during normal/cruise
11 and 21 drive propeller 13 and 23, axle translator via change speed gear box 12 and 22 respectively
14 and 24 are operated in Generator Status, by current transformer 33 and 43 direct current network on ship
Power supply.In particular cases, as unavailable in sustainer 11 and 21 or in ice formation etc. waters boat
OK, then axle translator 14 and 24 enters electric motor operation state, and current transformer 15 and 25 will
Electric power power shaft translator 14 and 24 in electrical network make its as puopulsion equipment, individually or with
Sustainer 11 and 21 acts on jointly, provides necessary propulsive force for boats and ships.This mixing
The mode advanced, coordinates the operating condition of half latent cargo ship, it is possible to effectively reduce fuel consumption,
Improve operational efficiency.When axle translator electric operation, Ship Propeling reliability can be improved
And propulsion capability, meanwhile, the electronic startup of sustainer can also be realized under special circumstances.
When the sustainer of side, such as when sustainer 11 is unavailable, this side can make
It is driven by the electric power of electrical network with axle translator 14.So make system flexibility and
Better reliability.Preferably, properly functioning sustainer 21 can pass through axle translator
24 generate electricity, and by current transformer 25 and and axle translator 14 between direct connection direct current
Bus 50, drives the axle translator 14 of unavailable side to carry out auxiliary propulsion, and optional with
Main electrical network cuts off operation, to reduce loss and interference.
Electrical load 10 on ship is by main generator 32 and 42 and axle translator 14 He
24 power supplies.Under different operating modes, electric energy is from axle translator 14 and 24, main generator 32
With 42 or both are in parallel.By using axle translator, sustainer 11 can be made full use of
With 21 available excess energies, improve engine efficiency.Constant at total electricity used
In the case of, the power of assisted engine 31 and 41 can be reduced or reduce its quantity.By
In assisted engine 31 and 41 and main generator be mounted on bow, the generating in bow portion
Board number and capacity are greatly decreased, thus inhabitation and working environment noise are greatly reduced.
System that employs direct current network.Compared with AC network, direct current network can be saved
Fuel, reduce discharge, improve systematic function, reduce maintenance cost, be easy to new forms of energy access,
Make axle translator and main generator be incorporated into the power networks to be more prone to and reliably simultaneously.Additionally, coordinate
Suitable control strategy and harmonious protection, the dc distribution network structure of annular can be according to need
Want, operate in open loop situations or closed loop states, optimize power supply reliability and the motility of system.
Owing to using direct current network, fairing and variable-speed generator, electromotor can be according to load
Situation works in different rotating speeds.This is possible not only to effectively reduce fuel consumption, it is also possible to improve
Generator operation efficiency, especially in the case of underload rate.
Additionally, propeller 13 and 23 can use the structure of controllable pitch propeller, such that it is able to
When low propelling load, it is used for generating electricity by more sustainer redundant power.This not only may be used
To improve the efficiency of electromotor, it is also possible to reduce in the quantity of net electromotor, save fuel and
Maintenance cost.
Oil consumption and maintenance cost analysis for a kind of parent ship show, with existing typical scenario
Compare, use the design can save the oil consumption of nearly 16%, and significantly reduce and safeguard into
This.
Should be appreciated that sustainer, change speed gear box, propeller and the connected mode of axle translator
It is not limited to the mode shown in figure, but can be to take various modes as shown in Figure 2.
Above-described is only principle of the present utility model and preferred embodiment, and it describes relatively
For concrete and detailed, but therefore can not be interpreted as the limit to this utility model the scope of the claims
System.It should be pointed out that, for the person of ordinary skill of the art, without departing from this
On the premise of utility model design, it is also possible to making some deformation and improvement, these broadly fall into
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be with institute
Attached claim is as the criterion.
