Development of Train Operation Power Simulator Reproducing Commercial Operation

In recent years, railway companies have been introducing energy-saving technologies. This is leading to a growing need for methods able to accurately estimate the energy-saving effect of individual technologies. To this end, RTRI and JR West have been developing a method to estimate energy consumption during train operation using the Train Operation Power Simulator which reproduces commercial operating conditions. Because of the dispersion of energy consumption in commercial operations, it is important to be able to faithfully reproduce commercial operations. Therefore, we have developed a method to reproduce commercial operation utilizing commercial running data obtained from a Train Data Collection Device. Moreover, we have achieved a practical calculation time to estimate the energy-saving effect.
