Abstract

The possibility of equipping a shunting diesel locomotive with an inert-capacitive energy storage device is being considered, which will smooth the load on the power plant and thereby reduce its power and mass and dimensions. The relatively frequent change in the operating mode of a shunting locomotive determines the efficiency and feasibility of equipping it with an energy storage device. In addition to smoothing the load on the power plant, the drive will allow energy to be recovered during braking, thereby increasing the energy efficiency of the shunting diesel locomotive. The theoretical background for creating an inert-capacitive energy storage device, which is technically designed as a DC machine with a super flywheel, is presented. The use of flywheels on shunting diesel locomotives is justified by virtue of not rigid requirements for the total weight. Another advantage of the locomotive is the presence of an electromechanical transmission, which minimizes the development for it of the considered inert-capacitive drive
