METHOD FOR REGULATING SPEED LOCOMOTIVE WITH ELECTRIC TRANSMISSION Russian patent published in 2017 - IPC B60L15/20 B60L11/02 

FIELD: electricity.

SUBSTANCE: method to control the speed of the locomotive with electric transmission is that emits a signal proportional to the actual speed, allocate a signal, which is proportional to the actual speed of the magnetic flux of the traction motor, calculate the movement resistance by the given values of the weight of the locomotive with the compound and profile of the movement area. According to the calculated value of the movement resistance and the known characteristics of the motor determine the setting of the traction current generator. Multiply the signal value proportional to the magnetic flux of the motor, with the magnitude of the setpoint speed, the obtained result is taken as the setpoint voltage of the generator. The acceleration of the locomotive is calculated, the calculated value is normalized and summed with a signal value, which is proportional to the actual speed. The result is compared with a predetermined value, the comparison result is integrated, by the result of the integration calculated set-point voltage of the generator is corrected and adjusted the voltage of the generator.

EFFECT: improved accuracy and speed of regulating the locomotive motion speed.
