The impact of the type of operation on the parameters of a shunting diesel locomotive with hybrid power plant

Abstract

Abstract. In designing a traction vehicle it is necessary to take into account the type of field operation it is meant for. It was found out that during shunting operation a ChME3 diesel locomotive is in idling mode for almost half of its general running time. That is why, the introduction of a less powerful engine along with an energy storage device for shunting operations at a shunting diesel locomotive is appropriate. The calculations were made using a modernized shunting diesel locomotive ChME3 with hybrid transmission of power as an example. The dependences of the general running time of a diesel locomotive on the position of the engine driver controller under performing shunting, transportation and hump operation were given in percentages. For every operation mode there was calculated the optimum power of a diesel-generator plant and the optimum energy capacity of an energy storage system taking into account the above-mentioned dependences. It was found out that due to the introduction of a hybrid drive for the section discussed above and the corresponding mass of a train the aggregate fuel consumption will be reduced by 25% and the efficiency of travel will increase by one third.

Model for building traction information of suburban rolling stock on hydrogen fuel

“…VNIIZhT scientists propose the use of hydrogen on the rolling stock of Russian railways [14]. Variants of the use of hybrid power plants on the modernized rolling stock in Ukraine are considered in [15][16][17][18][19].…”

Determining the parameters of a shunting locomotive taking into account the environmental component

“…The issues of modernization of shunting locomotives with hybrid power plants were considered by scientists of the Ukrainian State University of Railway Transport in [8][9][10]. They provide methods for determining the main characteristics of a locomotive with a hybrid power plant, but the environmental component is not sufficiently taken into account.…”

Development of the analytical system for vehicle operating conditions management in the V2I information complex using simulation modeling

“…[1,[13][14][15][16][17][18][19]]. The tasks listed and similar to them are still mainly solved by outdated methods that no longer provide the required quality, rational approach and efficiency [20][21][22]. Evaluation of operating conditions and analysis of road plans and profiles are usually performed manually; updates of maps and diagrams are extremely rare; data on the state of most objects are not systematized and thus difficult to access.…”
