Description
Technical field
The present invention relates to locomotive, relate in particular to a kind of voltage-operated device that is used for hybrid locomotrives.
Background technology
Oil electric mixed dynamic shunting locomotive of the prior art is as a kind of locomotive that utilizes new forms of energy, and its power provides part to have following two characteristics:
1, adopted the diesel-engine generator system to add power accumulator provides traction power jointly to locomotive mode.For general shunting locomotive, its mean load is lower, and power accumulator can store a large amount of electric energy, and sustainable bigger power is provided, so the diesel-engine generator system can select lower power for use.
When 2, locomotive was worked under the hybrid power operating mode, the voltage of battery pack can change with the variable power of battery charge, discharge, and the exciting current that generally adopts locomotive microcomputer to regulate the diesel-engine generator system comes the output voltage of regulator generator.If the diesel-engine generator output voltage can not be followed the variation of storage battery output voltage fast, will cause the charge and discharge electric current fluctuation of storage battery, total system also is difficult to stable work.
Summary of the invention
The objective of the invention is to be difficult to follow fast the variation of storage battery output voltage to the output voltage of above-mentioned diesel-engine generator; Cause the charge and discharge electric current fluctuation of storage battery; Cause system's problem of unstable, a kind of voltage-operated device that is used for hybrid locomotrives is provided.
The object of the invention is realized through following technical proposals:
A kind of voltage-operated device that is used for hybrid locomotrives; Comprise locomotive microcomputer, battery management system, battery pack, diesel powerplant, rectifying circuit, main convertor; Said locomotive microcomputer connects main convertor, and said locomotive microcomputer connects battery pack through battery management system, and said diesel powerplant connects main convertor through rectifying circuit; Said main convertor connects outside traction electric machine, and said locomotive microcomputer connects rectifying circuit.
Preferably, above-mentioned locomotive microcomputer is carried out communication through MVB and rectifying circuit.
Preferably, above-mentioned rectifying circuit is the four-quadrant rectifying circuit.
Preferably, above-mentioned diesel-engine generator is a three-phase 380/480V diesel-engine generator.
Beneficial effect of the present invention: because rectifying circuit can accurately control the diesel-engine generator horsepower output, the horsepower input of main convertor is also controlled fully, so the charge and discharge power of storage battery also is in slave mode, and the system that makes is in stable mode of operation.
Description of drawings
Fig. 1 is used for the voltage-operated device structural representation of hybrid locomotrives for this use is later-model.
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.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the present invention is further described.
The voltage-operated device structural representation that is used for hybrid locomotrives as shown in Figure 1; A kind of voltage-operated device that is used for hybrid locomotrives; Comprise locomotive microcomputer, battery management system, battery pack, diesel powerplant, rectifying circuit, main convertor; Said locomotive microcomputer connects main convertor, and said locomotive microcomputer connects battery pack through battery management system, and said diesel powerplant connects main convertor through rectifying circuit; Said main convertor connects outside traction electric machine, and said locomotive microcomputer connects rectifying circuit.Adopt diesel powerplant to send three plase alternating current, convert alternating current into direct current (DC) through rectifying circuit.The expected value that locomotive microcomputer is sent horsepower output to rectifying circuit, rectifying circuit requires the corresponding electric power of output according to locomotive microcomputer, and main convertor is according to the horsepower input of the requirement control traction electric machine of locomotive microcomputer.When locomotive needed the mixing of oil electricity that power is provided, closed battery pack was to the contactless switch of intermediate dc circuit.Because rectifying circuit can accurately control the diesel-engine generator horsepower output, the horsepower input of main convertor is also controlled fully, so the charge and discharge power of storage battery also is in slave mode, and the system that makes is in stable mode of operation.
Preferably, said locomotive microcomputer is carried out communication through MVB and rectifying circuit.MVB (MVB) is that a kind of being mainly used in (but also not being to be exclusively used in) is to the serial data communications busses between the interconnect equipment that interoperability and interchangeability requirement are arranged.MVB (Multifunction Vehicle Bus), it is the part of train communication network TCN, the TCN network is made up of MVB+WTB.Communication between original locomotive microcomputer and the main convertor also is to use MVB, and therefore using MVB not communicate herein need increase any hardware cost.
Preferably, said rectifying circuit is the four-quadrant rectifying circuit.The four-quadrant rectifying circuit has the better controlling effect to voltage magnitude, the size of current of output.The galvanic electric power of three plase alternating current output after the control of four-quadrant rectifying circuit is controlled fully, and the vdc amplitude of output changes and changes automatically with the terminal voltage of battery pack.Because unsteady flow module controls precision is high, adjusting is rapid, has thoroughly solved the VR that in the past caused and lagged behind the output voltage of electrical generator, surge of current because of the remanent magnetism effect.
Preferably, said diesel-engine generator is a three-phase 380/480V diesel-engine generator.Three-phase 380/480V generator set belongs to the matured product of a large amount of supplies on the market, and it is reliable to possess skills, the advantage that cost is low.
More than above-mentionedly be merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
