Description
Technical field
The present invention relates to locomotive, particularly relate to a kind of voltage-operated device for hybrid locomotrives.
Background technology
Oil electric mixed dynamic shunting locomotive of the prior art is as a kind of locomotive utilizing new forms of energy, and its power provides part to have following two features:
1, have employed diesel generator system and add power accumulator provides traction power jointly mode to locomotive.For general shunting locomotive, its mean load is lower, and power accumulator can store a large amount of electric energy, and sustainablely provides larger power, and therefore diesel generator system can select lower power.
2, when locomotive works under hybrid power operating mode, the voltage of battery pack can change with the changed power of battery charge, electric discharge, and the general locomotive microcomputer that adopts regulates the exciting current of diesel generator system to carry out the output voltage of regulator generator.If diesel-engine generator output voltage can not follow the change of storage battery output voltage fast, will cause the charge and discharge electric current fluctuation of storage battery, whole system is also difficult to stable work.
Summary of the invention
The object of the invention is the change being difficult to follow fast storage battery output voltage for the output voltage of above-mentioned diesel-engine generator, cause the charge and discharge electric current fluctuation of storage battery, cause the problem of system instability, a kind of voltage-operated device for hybrid locomotrives is provided.
Object of the present invention is realized by following technical proposals:
A kind of voltage-operated device for hybrid locomotrives, comprise locomotive microcomputer, battery management system, battery pack, diesel powerplant, rectifying circuit, main convertor, described locomotive microcomputer connects main convertor, described locomotive microcomputer connects battery pack by battery management system, described diesel powerplant connects main convertor by rectifying circuit, described main convertor connects outside traction electric machine, and described locomotive microcomputer connects rectifying circuit.
Preferably, above-mentioned locomotive microcomputer carries out communication by MVB and rectifying circuit.
Preferably, above-mentioned rectifying circuit is four-quadrant rectifying circuit.
Preferably, above-mentioned diesel-engine generator is three-phase 380/480V diesel-engine generator.
Beneficial effect of the present invention: because rectifying circuit can accurately control diesel-engine generator horsepower output, the horsepower input of main convertor is also completely controlled, and therefore the charge and discharge power of storage battery is also in slave mode, makes system be in stable mode of operation.
Accompanying drawing explanation
Fig. 1 is the novel voltage-operated device structural representation for hybrid locomotrives of this use.
Wherein 1 is locomotive microcomputer, and 2 is battery management system, and 3 is battery pack, and 4 is diesel powerplant, and 5 is rectifying circuit, and 6 is main convertor, and 7 is outside traction electric machine.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the present invention is further illustrated.
The voltage-operated device structural representation for hybrid locomotrives as shown in Figure 1, a kind of voltage-operated device for hybrid locomotrives, comprise locomotive microcomputer, battery management system, battery pack, diesel powerplant, rectifying circuit, main convertor, described locomotive microcomputer connects main convertor, described locomotive microcomputer connects battery pack by battery management system, described diesel powerplant connects main convertor by rectifying circuit, described main convertor connects outside traction electric machine, and described locomotive microcomputer connects rectifying circuit.Adopt diesel powerplant to send three plase alternating current, through rectifying circuit, alternating current is converted to direct current (DC).Locomotive microcomputer sends the expected value of horsepower output to rectifying circuit, and rectifying circuit requires to export corresponding electric power according to locomotive microcomputer, and the requirement of main convertor foundation locomotive microcomputer controls the horsepower input of traction electric machine.When the mixing of locomotive needs oil electricity provides power, closed battery pack is to the contactless switch of intermediate DC circuit.Because rectifying circuit can accurately control diesel-engine generator horsepower output, the horsepower input of main convertor is also completely controlled, and therefore the charge and discharge power of storage battery is also in slave mode, makes system be in stable mode of operation.
Preferably, described locomotive microcomputer carries out communication by MVB and rectifying circuit.MVB (MVB) is that one is mainly used in (but being also not exclusively used in) to the serial data communications busses between the interconnect equipment having interoperability and an interchangeability requirement.MVB (Multifunction Vehicle Bus), it is a part of train communication network TCN, and TCN network is made up of MVB+WTB.Communication between original locomotive microcomputer and main convertor is also use MVB, therefore uses MVB to carry out communicating and do not need to increase any hardware cost herein.
Preferably, described rectifying circuit is four-quadrant rectifying circuit.Four-quadrant rectifying circuit has good control effects to the voltage magnitude exported, size of current.The galvanic electric power that three plase alternating current exports after four-quadrant rectifying circuit controls is completely controlled, and the vdc amplitude of output changes automatically with the terminal voltage change of battery pack.Because unsteady flow module controls precision is high, regulate rapidly, thoroughly solve the voltage-regulation in the past caused because of left magnetic effect delayed, the output voltage of electrical generator, surge of current.
Preferably, described diesel-engine generator is three-phase 380/480V diesel-engine generator.Three-phase 380/480V generator set belongs to the matured product of a large amount of supply on market, possesses skills reliable, the advantage that cost is low.
More than above are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
