It is that diesel engine can not rapidly follow change, cause diesel engine operating condition poor, fuel consumption when ship load is varied widely
Defect high.The sharpest edges of this scheme are equipment costs than less expensive.In order to save marine shafting arrangement space, ship is improved
The electrically driven response speed of oceangoing ship and controllability, have developed ship exchange networking electric propulsion system, i.e. diesel engine drives same
Step electrical power generators, the constant frequency and constant voltage alternating current of generation carries out exchange networking, the exchange after exchange networking by alternating-current distribution panel
By after ac-dc-ac frequency converter, driving ship propulsion motor work, propulsion motor is driving marine propeller to voltage
Promote vessel motion.When ship load changes, because synchronous generator has output with frequency with pressure constant AC voltage
The characteristics of, the change of bearing power can only be adapted to by way of cutting off or increasing synchronous generator, due to this switching side
Formula is nonlinear, can cause the diesel engine of operation and can not operate on optimal power efficiency point, there is fuel oil utilization rate pole
Its low problem.Additionally, the control system of the alternating-current distribution panel both sides of exchange networking propulsion system is individually designed control,
There is the control that the control of diesel generating set assists with moving system to isolate, the integration of whole system is poor, and equipment is taken up an area empty
Between it is big, equipment price is high.Because direct current networking electric propulsion system is to change to increase and decrease diesel generating set according to load
Quantity come adapt to bearing power change, in some special ships, due on ship lay the device space be limited, it is impossible to lay
More diesel generating set, making the laying of existing direct current networking electric propulsion system cannot realize.Most of ship is in height
The loading load state status duration is not long, if pressing higher load condition design propulsion system, can form redundance unit excessive.

Device is connected with common DC bus, and ship side pushing motor is connected by another inverter with common DC bus, is realized
Ship load is when changing, can Serial regulation asynchronous generator generated output, diesel oil function is operated in optimal fuel oil
In the state of power consumption, and network of ship is operated under normal operating voltage, improve the efficiency of combustion of diesel engine, improve
Generate electricity and promote two integrations and harmony of link.Under ship heavy-duty service state, by configuring batteries
Instead of diesel generating set, play saving ship equipment and lay space, reduce the effect of ship investment cost.
A kind of ship direct current networking propulsion system with batteries to store energy, including the first diesel generator group and second
Diesel generator group, the first diesel generator group is connected by the first rectifier with common DC bus, the second diesel engine
Generating set is linked together by the second rectifier and common DC bus, is connected on common DC bus and promoted mainly
Stepper motor inverter and side propulsion electric machine inverter, are connected with main pushing motor on main propulsion motor inverter, promoting mainly dynamic electricity
Main thruster is connected with machine, side propulsion electric machine inverter is connected with side pushing motor, and being connected with side on the pushing motor of side pushes away
Enter device；Chopper is connected with common DC bus, batteries are connected with chopper.
The daily power inverter of ship is connected with common DC bus, the daily power inverter of ship passes through transformer
Load daily with ship is connected.
The present invention has integrated level higher, and relatively low cost, number of devices is few, and floor space is small and lightweight.This hair
It is bright to access the requirement that batteries meet high load capacity in marine propuision system high loaded process, when running well,
Cut-out batteries, make each equipment of direct current networking give full play to its efficiency.
