Speed Profile Generator for Energy Estimation of a Train Running Simulator

Abstract

Energy estimation of a train running simulator is useful for evaluating the effect of energy saving devices. The energy estimation requires the calculation of a speed profile representative of those based on various driving operation between two stations from a point of view of energy consumption. We developed a speed profile generator for a train running simulator, and it generates a speed profile for energy estimation. In contrast to a speed profile used for timetable planning, which shows the shortest possible running time between stations, the speed profile for energy estimation is calculated when the running time is given and it result in average energy consumption. The developed speed profile for energy estimation validates the good agreement of the energy consumption with the various commercial running data. Furthermore, we developed a method to extract a typical group of measured speed profiles from commercial running data. The speed profiles for energy estimation correspond to the typical group of measured speed profiles.
