Abstract

Fuel Cell Hybrid Electrical Vehicles (FCHEVs) have established commercially due to their inherent advantages such as pollution free, environment friendly and use of renewable energy. FCHEVs are now slowly but steadily entering rail transportation. Optimum selection of power ratings and combination of energy sources used in FCHEVs are of utmost importance, because of expensiveness. Various techniques have been used for optimization of energy consumption based on either historical performance data or specified duty cycle of given route. This study presents a new approach to find out optimum energy of vehicle on particular route by simulating its performance considering influence of route profile and operational restriction. Influence of these factors are presented individually as well as simultaneously on performance of traction drive and their impact on net energy consumption, travel time, RMS current and speed profile. This will help in selection of optimum rating and combination of energy sources required for given performance of FCHEV for rail application. Simulation results will also serve as an evaluation tool for validation of design and prototype testing in the absence of any standard protocol for rail operation unlike FTP-75 for road vehicles.
