Energetic Macroscopic Representation of a hybrid railway powertrain

Due to its railroad activities, the SNCF (French National Railway Company) tries to anticipate oil rarefaction and to improve its commitment in environment protection. Thus, its research program in energetics deals with the hybridization of the railway powertrains and substations. One of the problems identified is the design and the control (local and global) of a multi sources and multi-storage system. To solve this problem, an Energetic Macroscopic Representation (EMR) and a Maximal Control Structure (MCS) of each element of the system is presented. Then, results of an energy management strategy based on filtering are proposed and discussed.
