Direct drive marine propeller, promotes vessel motion, and its propulsion system is made up of diesel engine, decelerator and propeller.Diesel oil
Together with the main shaft of machine is directly connected to propeller shaft, there is shafting and take up room greatly, the strong problem of vibrating noise.Especially
It is that diesel engine can not rapidly follow change, cause diesel engine operating condition poor, fuel consumption when ship load is varied widely
High defect.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 electricity of generation carries out exchange networking by alternating-current distribution panel, exchanges the alternating voltage after networking
After ac-dc-ac frequency converter, drive ship propulsion motor, propulsion motor to drive marine propeller, promote ship fortune
OK.When load changes, because synchronous generator has the characteristics of exporting pressure constant AC voltage same with frequency, can only pass through
Cut-out increases the mode of synchronous generator adapting to the change of bearing power, because this switching mode is nonlinear, meeting
Cause the diesel engine for running to operate on optimal power efficiency point, there is a problem of that fuel oil utilization rate is extremely low.This
Outward, the control system in the alternating-current distribution panel both sides of exchange networking propulsion system is individually designed control, there is diesel generation
The defect of inaccurate coordination between the control of unit and the control of moving system, the integration of whole system is poor, and equipment takes up an area face
Product is big, and price is higher for traditional diesel oil propulsion.
With the progress of technology, a kind of ship direct current networking electric propulsion system is occurred in that, concrete structure is：Using diesel oil
Machine drives an asynchronous generator to be generated electricity, and respective exchange is all connected with the outfan of every asynchronous generator and is straightened
The commutator of stream, the direct current after rectification is connected on a common DC bus, is parallel with the common DC bus multiple
Inverter, is connected with respective Ship Propeling motor on each inverter, each Ship Propeling motor and respective Ship Propeling
Device links together.When ship load change when, can every diesel engine of dynamic regulation rotating speed, control diesel engine transport all the time
Row is on optimum power efficiency point, that is, is under preferably fuel oil use state, greatly reduces diesel engine
Oil consumption.Especially since by the way of common DC bus, make load change can by the rotating speed of asynchronous generator come
Neatly linearly adjust, the fluctuation without causing common DC bus DC voltage, and then also do not interfere with ship
The normal operation of each electricity consumption electrical network.Before direct current networking electric propulsion system input vessel motion, it is required on land to it
Performance and index carry out necessary combined test, to facilitate the normal mounting operation on ship of direct current networking electric propulsion system.
Existing adjustment method is that the input side of direct current networking electric propulsion system is equipped with into diesel engine unit to be generated electricity, by propulsion electric machine
Propeller afterwards simulates replacement with electromotor loading, and such debud mode can cause substantial amounts of energy expenditure, diesel engine
Can also discharge of noxious gases, debugging cost is high.
The content of the invention
