The Use of a Hybrid Powertrain on Suburban Diesel-Electric Multiple Units

Abstract

The paper is aimed at determining the feasibility of using energy storage in hybrid power units of domestic diesel trains. The calculations are made for the diesel-electric multiple unit DEL-02 with electric power transmission. A mathematical model of the train’s movement was developed and the simulation of the movement of the diesel-electric multiple unit DEL-02 was carried out on the section between the stations Liubotyn and Boromlya (Ukraine). According to the results of the calculations, it was found that the work of electrodynamic braking forces is 26…30% of the tangential work performed in the traction mode. The actual accumulation will be slightly lower due to energy losses during the process of charging the energy storage device. It has been determined that the most common application is the accumulation of energy during electrodynamic braking and the supply of a traction electric drive during subsequent acceleration. Another option is the use of a plug-in system. To select a rational option for the use of an energy storage device, it is necessary to determine the fuel consumption taking into account the control strategies of a hybrid powertrain.
