Description
Technical field
The present invention relates to power concentration EMU power supply control technical fields, and in particular to the power collection that one kind is flexibly organized into groups
Middle motor train unit train method for controlling power supply.
Background technique
Power concentration EMU is a kind of economical stronger motor train unit train, and utilization and maintenance cost are all than traditional motor-car
Group is superior.Power concentration EMU difference compared with power-decentralized TDMU mainly all collects in the power of power concentration EMU
In on power car, by the power car traction not compartment of drive and fixed marshalling is used, main dynamics equipment also concentrates on moving
On power vehicle, passenger is not carried on power car.There is no power-equipment on control vehicle, only plays the work of control permutation EMU operation
With controlling and carry passenger on vehicle, the marshalling type of power concentration EMU is flexibly 1+1, the compartment of power car+n power
Vehicle/1 control vehicle (16 >=n >=0) or 1+1, compartment control vehicle of power car+n (8 >=n >=0).Due to not having on control vehicle
Dynamic equipment, so train power supply device is also contained on power car, control vehicle, which does not have, carries out train confession to permutation EMU
The ability of electricity.So using+n compartments of 1+1, the compartment of power car+n power car (16 >=n >=0) or 1 power car
The mode of two kinds of train power supplies in the case where+1 control vehicle (8 >=n >=0) has differences.
Since the train power supply power supply in compartment is that left and right road supply cell uses, so when carrying out train power supply to compartment
Needing two-way power supply has the ability of power supply.So two kind volumes of the existing train power supply control method in power concentration EMU
It is not suitable in group mode.
Summary of the invention
The present invention provides a kind of power concentration motor train unit train method for controlling power supply flexibly organized into groups, and it is dynamic to meet power concentration
Vehicle group is controlled using 1+1, the compartment of power car+n power car (16 >=n >=0) or 1+1, compartment of power car+n
The automatic conversion of the mode of two kinds of train power supplies in the case of two kinds of marshallings of vehicle (8 >=n >=0).
The technical scheme adopted by the invention is that the power concentration motor train unit train method for controlling power supply flexibly organized into groups, power
The organizational systems of EMU are concentrated to be divided into long marshalling and short marshalling, length is organized as 1+1, the compartment of power car+n power car (16
>=n >=0) organizational systems, the short organizational systems for being organized as 1+1, compartment control vehicle of power car+n (8 >=n >=0), power
Train power supply power supply device LGU1, LGU2 and train power distribution are provided on vehicle, train power distribution is matched for train power supply
Fulgurite is managed, the on-off of the contactor KM1 control train power supply power supply device LGU1 in train power distribution, contactor KM3 control column
The on-off of vehicle power supply device LGU2, after contactor KM2 controls train power supply power supply device LGU1 and LGU2 power sources in parallel
On-off is provided with grouping formulation switch on train power distribution, and when selecting short marshalling, KM1 and KM3 closure, KM2 are disconnected,
LGU1 and LGU2 conveys electric energy to compartment respectively, and when selecting long marshalling, KM1 and KM2 closure, KM3 are disconnected, and LGU1 and LGU2 divide
Electric energy is not conveyed to compartment.
The train power distribution is provided with control unit, for receiving grouping formulation switching signal, control contactor
Closure and disconnection.
The beneficial effects of the present invention are: the power concentration motor train unit train method for controlling power supply flexibly organized into groups makes power concentration
EMU meets requirement of the compartment to train power supply, at the same also ensure flexibly marshalling in the case of, train power supply control from
Dynamic switching.

Specific embodiment
It is described further now in conjunction with attached drawing 1 to 4 pairs of inventions of attached drawing, is+n compartments+1 of 1 power car as shown in Figure 3
Platform controls the train power supply control principle drawing of the organizational systems of vehicle (8 >=n >=0), since control vehicle 5 is filled without train power supply
It sets, so control vehicle 5 does not have the ability of train power supply.LGU1, LGU2 are on power car 1 in two sets of train power supply power supplys having
Device, column power supply and distribution cabinet mainly realize that the distribution management of train power supply, KM1, KM2, KM3 are to realize train power supply distribution management
Contactor.The load in compartment 3 is smaller in this mode, and a power car is just able to satisfy the demand in compartment 3 to compartment power supply.
It is the train power supply control principle of the organizational systems of 1+1, the compartment of power car+n power car (16 >=n >=0) as shown in Figure 4
Figure, since power car 1 has train power supply device, so two power cars 1 are provided with the ability of train power supply.In such mould
The load in compartment 3 is larger under formula, needs two power cars to power simultaneously to compartment 3 and is just able to satisfy the demand in compartment 3.
Specific as follows: the power supply and compartment rearwards that LGU1 output can be connected after KM1 contactor closure convey electric energy.
KM3 contactor closure after can connect LGU2 output power supply and rearwards compartment 3 conveying electric energy.Meeting after KM2 contactor closure
The compartment 3 of the power sources in parallel of LGU1 and LGU2 rearwards is exported into electric energy.Grouping formulation switch is provided on train power distribution,
It is divided into short marshalling and long marshalling, the long organizational systems for being organized as 1+1, the compartment of power car+n power car (16 >=n >=0) are short
The organizational systems of 1+1, compartment control vehicle of power car+n (8 >=n >=0) are organized as, after grouping formulation switch is selected, train
After the control unit of power distribution cabinet receives grouping formulation switching signal, contact can be controlled according to specified contactor control program
The closure and disconnection of device.Main implementation means, which are exactly train, to be received after mode selection command with electric control unit according to specified
Contactor controls program to export direct current 110V power supply to the control coil of contactor, exports direct current 110V power supply to control contact
The closure of device disconnects the disconnection that direct current 110V power supply carrys out control contactor.
In the case where having selected " power car+compartment+control vehicle " mode in short marshalling, KM1 and KM3 closure
KM2 is disconnected.LGU1 and LGU2 conveys electric energy to compartment 3 respectively, this electric energy is used for all kinds of loads in compartment 3.In short marshalling situation
Under, since control vehicle 5 is there is no LGU1 and LGU2, so control vehicle does not have power output.Power car 1 by two sides to
Compartment 3 exports electric energy, and since power car 1 is that head and the tail are hung together, there are power supply submitting in permutation marshalling two sides under this grouping formulation, and
Since KM2 is not closed, the parallel connection of two-way power supply is not formed, is independently powered.
In the case where having selected " power car+compartment+power car " mode in long marshalling, KM1 and KM2 closure,
KM3 is disconnected.LGU1 and LGU2 conveys electric energy to compartment 3 respectively, this electric energy is used for all kinds of loads in compartment 3.Situation is organized into groups long
Under, each power car 1 exports electric energy to compartment 3 by right side, since power car 1 is that head and the tail are hung together, under this grouping formulation
There are power supply submitting in permutation marshalling two sides, and since KM3 is not closed, do not form the reverse irrigation of electric energy.
