Abstract
The reduced electricity consumption for train traction has been and it is one of the priorities of the Russian Railways. One of the ways to reduce electricity consumption is the rational driving of trains in traction mode which depends on both the locomotive crew and the design of the electric rolling stock. In fact, the faster the train accelerates, the faster it stores kinetic energy, and its optimal use will reduce electricity consumption. At present, for additional acceleration, modern domestic electric locomotives use a system for weakening the excitation of the traction motors. In this paper, a traction calculation is carried out, which makes it possible to compare the consumption of electricity during the acceleration of a train during the operation of an electric locomotive with stepwise and smooth regulation of the weakening of the excitation of traction motors. With the help of traction calculation during the acceleration of the train, the energy efficiency of the excitation attenuation system with smooth control of the excitation of the electric locomotive was proved.
