METHOD OF CONTROLLING DIESEL LOCOMOTIVE ELECTRIC POWER TRANSMISSION Russian patent published in 2013 - IPC B60L11/00 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to control over transmission of electric power. Proposed method consists in setting rpm of heat engine driving sync traction generator, and varying the position of fuel feed proportioner of rpm controller and that of heat engine corresponding to its rpm. Said fuel feed proportioner position is set proportional to preset heat engine rpm to compare it with measured position while mismatch magnitude is integrated in time to set constant excitation current of sync generator. Said excitation current of sync generator is set to maximum as a function of measured position of fuel feed proportioner, measured fuel feed proportioner and its preset position mismatch is integrated in time and taken to ne appropriate setting of traction motor rpm to compare traction motor rpm with rpm setting. Results of comparison is amplified and taken to be setting corresponding to controlled rectifier output voltage setting and is fed to control input to control output voltage phase. Said output voltage is fed to traction motor input. Measured rpm of traction motors are corrected with due allowance for correction factors in selected time intervals whereat diesel locomotive runs in stopping mode.

EFFECT: higher efficiency.
