Staff members of the Department, Assoc. Prof. Liliia Overianova and Yevhen Riabov, together with PhD candidates Volodymyr Neshcheret and Andrii Podoliak, took part in the 16th International Conference TRANSBALTICA 2025: Transportation Science and Technology (September 18–19, 2025, Vilnius | Klaipėda, Lithuania).
They presented a paper entitled “Substantiation of the Rational Operating Mode of a Hybrid Power Plant for a Diesel Train.”
For the efficient use of hybrid power plants in rolling stock, it is essential to determine their rational operating modes. Fuel consumption is proposed as the main criterion for evaluating efficiency.
The study suggests using the comparative fuel consumption required to generate one kilowatt-hour of energy under different load supply methods. Two scenarios were considered: direct power supply of the traction system from a diesel generator, and supply from an energy storage system previously charged by the diesel generator.
Using the example of the DEL-02 diesel train, it was shown that when powered from the energy storage system, the comparative fuel consumption at the zero and first controller positions is 0.234 g/kWh, which is lower than the 0.3 g/kWh recorded for direct supply from the diesel generator. Therefore, at the zero and first controller positions, it is advisable to power the traction system from the energy storage system. At higher controller positions, however, power should be supplied directly from the diesel generator, as in this case the comparative fuel consumption is lower.
The proposed method, which takes into account fuel consumption for generating one kilowatt-hour of energy under different load supply methods, makes it possible to determine the rational operating mode of a hybrid power plant and can be extended to other types of rolling stock.
