METHOD OF ADJUSTING DIESEL LOCOMOTIVE ELECTRIC TRACTION TRANSMISSION Russian patent published in 2011 - IPC B60L11/00 H02P9/00 

FIELD: transport.

SUBSTANCE: code signal is fed to inputs of revolution controller and thermal engine, traction generator power setting unit and traction generator power setting selecting unit. Position of fuel feed meter incorporated with rpm regulator fuel feed and thermal engine load meter is set. Signal of preset position of fuel feed meter incorporated with rpm regulator fuel feed and thermal engine load meter is compared with measured value. Traction generator power is set in proportion to measured rpm of thermal engine rpm. Preset power is added to the result of integrating mismatch between preset and measured position of fuel feed metering device of rpm controller and thermal engine. Result of addition is taken to be setting for traction generator power. Code signal is compared with preset setting. Results of comparison are used to switch over traction generator power setting generation channels. Voltage across traction motor serial excitation windings is defined. Voltage difference at serial excitation windings is measured and differentiated with retardation. Signal proportional to measured voltage of traction generator is compared with traction generator voltage setting. Traction generator excitation current is varied depending upon measured mismatch of traction generator voltage.

EFFECT: smooth acceleration in start-off.
