Abstract
The transient processes caused by changes in the operating account a significant proportion of the operating time of the locomotive diesel generator equipment. At the same time, in traction calculations, the change in power and fuel consumption by the power plant is assumed to be instantaneous, which can lead to a decrease in their reliability. The methods of statistical processing and regression analysis of experimental data were used in the work. Based on the statistical analysis of the registration data of the on-board diagnostics subsystem of 2TE116U locomotives, a methodology for taking into account the influence of transients on the power plant power level and fuel consumption is proposed and justified. The results obtained make it possible to clarify the parameters of the traction characteristics of the locomotive and can be used when performing operational traction calculations.
