Need to carry out the traction electric machine 1 of State Transferring according to the number of axle of locomotive and traffic direction selection, when locomotive is six axles
During locomotive, the traction electric machine 1 of the second axle or the 5th axle is carried out between series excitation DC traction motor and separate excitation dc generator
Conversion；When locomotive is four axle locomotive, to the traction electric machine 1 of the second axle or the 3rd axle carry out series excitation DC traction motor with
Conversion between separate excitation dc generator.
Before traction electric machine 1 enters generating state, power management module 2 carries out real-time to 6 groups of terminal voltages of locomotive storage batteries
Monitoring, when the voltage of locomotive storage batteries 6 is less than DC86V, power management module 2 controls locomotive storage batteries 6 to stop to ac converter
Module 5 conveys the power supply that power supply cancels locomotive load, to ensure the supply of field power supply.
Power management module 2 is monitored in real time to the charging and discharging currents of locomotive storage batteries 6, avoids the mistake of locomotive storage batteries 6
Fill or cross and put.
Power management module 2 is right before control excitation copped wave module 4 provides field power supply using the power supply of locomotive storage batteries 6
Locomotive operation direction is detected, the sense of current exported according to locomotive operation direction controlling excitation copped wave module 4, so as to lead
Draw the field power supply that motor 1 provides correct direction.
Power management module 2 monitors to locomotive without fiery state, when locomotive starts Electrical key, power management module
2 alarm and the order that is stopped are sent to electric supply installation to terminate the generating state of traction electric machine 1.
Power management module 2 monitors to the running status of locomotive, when locomotive running speed is less than preset value or inspection
When the Current Voltage value of each module measured occurs abnormal, power management module 2 is alarmed and sent to electric supply installation and is stopped
Order to terminate the generating state of traction electric machine 1.
The preset value of locomotive running speed is 20km/h-120km/h.
Because the major factor for influenceing generating voltage has：The setting value of motor energization current, motor speed and voltage, according to
The electromagnetic torque fundamental formular of direct current generator：
M=CmØIZ （1）
In formula：Cm- torque constant
- per pole magnetic flux
IZ- armature supply
When the magnetic saturation for not considering motor influences with armature reaction, formula（1）Can be approximately：
M=CMILIZ （2）
In formula：IL- exciting current
According to the electric potential balancing equation of motor：
E=CenØ=IZ(Rz+ΣR) (3)
In formula：Ce- back EMF constant
N-motor speed
Rz-electric supply installation internal resistance
Σ R-armature winding and interpole winding all-in resistance
Therefore, the braking moment of motor can be expressed as：
According to locomotive brake characteristic requirements, also need to consider the maximum exciting current limitation of traction electric machine, the limitation of maximum stalling current,
The limitation of motor commutation voltage, motor adhesion restraining line and locomotive configuration rate limitation.20KW braking is being taken from traction electric machine
It is relative with hundreds of KW braking power easily during locomotive resistive braking during power, traction generate electricity caused by machine winding copper loss,
Resistive braking operating mode when armature voltage and brake force are far smaller than locomotive normal operation.
Above example is used for illustrative purposes only, rather than limitation of the present invention, the technology people about technical field
Member without departing from the spirit and scope of the present invention, can also make a variety of changes or convert, therefore all equivalent
Technical scheme should also belong to protection scope of the present invention, and protection scope of the present invention should be limited by each claim.
