Demandingness of the energy calculation by means of the rail vehicle momentary output time integration method lies in a need for detailed input data as a tachogram - a time-speed relation and a corresponding passed distance which can be obtained by a calculation or from a train entrepreneur. A locomotive load value, comprising wagons and resistance components of a track, determines a required tractive power value on a wheel circumference. Each traction power value is assigned to a traction motor current value in traction characteristics, which can be further used for a locomotive output calculation. To make the calculation more accurate a model has been created in the EMTP – ATP software, its advantage is to simulate a dynamic behavior of a model which is affected by more influences at the same time. The simulation time can be shortened in an exact ratio to the real time and thus an evaluation and implementation of changes of the model parameters can be performed more quickly.
