MICROPROCESSOR SYSTEM FOR DIESEL LOCOMOTIVE TRACTION GENERATOR VOLTAGE ADJUSTMENT Russian patent published in 2015 - IPC B60L11/04 

FIELD: transport.

SUBSTANCE: invention relates to diesel locomotive electric traction system generator voltage ACS at automatic locomotive control in motion. Microprocessor voltage control system comprises diesel-generator, exciter connected by rigid coupling with diesel and connected to traction generator excitation winding, voltage transducer, traction generator current transducer and diesel-generator shaft rpm transducer. Transducer of duel feed to diesel is connected with automatic diesel-generator shaft rpm controller. Exciter excitation unit is connected to exciter excitation winding. Pneumatic brake control unit comprises motion mode calculation and on-line data display unit and interface unit. Microprocessor controller includes first and second masters, first, second, third comparators, operating converter, first and second integrators, multiplier, logical device and adder. Operating converter input is connected with automatic diesel-generator shaft rpm controller output while its outputs are connected with first of third comparator and first input of adder. Second input of third comparator is connected with fuel feed transducer output while output of third comparator is connected with input of first integrator connected by its output with second input of adder.

EFFECT: optimiser speed of diesel locomotive.
