Different models of an energy storage subsystem for a hybrid locomotive

The aim of this paper is to determine an appropriate model of a hybrid diesel-electric locomotive in order to estimate its fuel consumption and test new energy managements. The locomotive is composed of a diesel-based generation subsystem, a battery - supercapacitors storage subsystem and a traction subsystem. A quasi-static model of the locomotive has been carried out from dynamical model. It allows the reduction of the computation time by 22 keeping an energy consumption accuracy of 99.4 %. Energetic Macroscopic Representation (EMR) is used as common description tool for the different models.
