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
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 electricity of generation carries out exchange networking, the alternating voltage after exchange networking by alternating-current distribution panel
By after ac-dc-ac frequency converter, driving ship propulsion motor, propulsion motor to drive marine propeller, ship fortune is promoted
OK.When load changes, because synchronous generator has the characteristics of exporting pressure constant AC voltage same with frequency, can only pass through
Cut off or increase the mode of synchronous generator to adapt to the change of bearing power, because this switching mode is nonlinear, meeting
Causing the diesel engine of operation can not 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 advances in 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 every output end of asynchronous generator and is straightened
The rectifier of stream, the direct current after rectification is connected on a common DC bus, and multiple is parallel with the common DC bus
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, without causing the fluctuation of common DC bus DC voltage, and then also do not interfere with ship
The normal operation of each electricity consumption power 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 direct current networking electric propulsion system normal mounting on ship to run.
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 generator loading, and such debud mode can cause substantial amounts of energy ezpenditure, diesel engine
Can also discharge of noxious gases, debugging cost is high.
The content of the invention
The invention provides a kind of land joint debugging system of ship direct current networking electric propulsion system, prior art is solved
The debugging cost existed when ship direct current networking electric propulsion system is debugged problem high and pollution environment.
A kind of land joint debugging system of ship direct current networking electric propulsion system, including power supply grid, power supply grid pass through
Accompany examination rectifier to be linked together with examination dc bus is accompanied, the DC side for accompanying examination inverter be connected with examination dc bus is accompanied,
Accompany the AC of examination inverter to be connected with and accompany examination motor, direct current networking is connected with the output shaft for accompanying examination motor and is generated electricity
Machine, is connected with direct current networking rectifier in the output end of direct current networking generator, the output end of direct current networking rectifier is by straight
Stream networking inverter links together with direct current networking motor, is connected with the axle of direct current networking motor and accompanies examination exchange hair
Motor, feedback rectifier is connected with the output end for accompanying examination alternating current generator, and the DC output end of feedback rectifier is with to accompany examination straight
Stream bus links together.
Central scope of the invention be with accompany examination motor replace the diesel engine of ship direct current networking electric propulsion system, use
Examination generator and feedback rectifier is accompanied to replace the propeller of ship direct current networking electric propulsion system.Examination rectifier is accompanied to power electric
The AC rectification of net starts energy and loss of energy into direct current to accompanying on examination dc bus for whole debugging system is provided.
It is that debugged ship direct current networking electric propulsion system is powered from acquisition electric energy on examination dc bus is accompanied to accompany examination inverter, accompanies examination
Generator and feedback rectifier are by the unnecessary electric energy feedback of ship direct current networking electric propulsion system to accompanying on examination dc bus.
In whole debugging process, electric energy is recycled in whole debugging system, and power consumption is only the loss of each equipment, is changed
Traditional adjustment method there is a problem of load consumption and waste the energy, in debugging system with accompany try motor replace diesel oil come
Drive direct current networking generator, it is to avoid diesel engine operates brought environmental pollution.
Present invention uses closed loop feedback debug circuit, make ship direct current networking electric propulsion system in test, from accompanying
Absorb the electrical energy drive of the needs system operation on examination dc bus, it is last again by unnecessary electric energy feedback to accompanying examination dc bus
On, electric energy is recycled in the debug circuit, has saved the energy, reduces discharge, reduces testing cost.
