One of the most important tasks of the strategic documents of "Russian Railways" OAO is to increase the freight turnover in the railway network by 42 % by 2025. One of the ways to achieve this goal is to increase the operating speed of freight trains. Currently, after reaching the maximum voltage at the 4th zone of regulation of the reversible converter, the speed is further adjusted by changing the magnetic flow by connecting the system of field weakening of the contactor-rheostat type in parallel to the excitation windings of the traction electric motor. The article discusses the disadvantages of this system. An analytical justification is provided for the fact that step-by-step switching of the electric locomotive traction motor field weakening results in the losses of speed and acceleration. To check this statement, the simulation of AC electric locomotive of the 2ES5K series with step-by-step and smooth adjustment of the traction electric motor field weakening was carried out in the software package "CORTES" while passing along the Zima–Irkutsk-Sortirovochny section. The simulation results showed that the smooth regulation of the traction electric motor field weakening provides an increase in the technical speed of an electric locomotive by at least 2.5 km/h. An advanced field weakening system for traction electric motors on the basis of modern power fully controlled IGBT-transistor semiconductor devices that provide smooth regulation of the excitation current is proposed. The use of this system will eliminate the disadvantages of the standard system of weakening the field of electric traction motors of an electric locomotive and increase the operating speed of an electric moving train by at least 2.5 km/h.
