摘要: Abstract A fuel cell-battery-supercapacitor powertrain, for railways, is investigated and numerically modelled. Each main powertrain component, such as energy sources, power electronic drivetrain components, analysed in detail; electrochemical, logic physic equations are used to design the models, formalizing implementing them Matlab-Simulink. To achieve a proper behaviour high performance, two control strategies implemented: an ad-hoc power-sharing system, designed that connects principles of global drive-cycle knowledge real-time methods; motor control, composed proportional-integral speed direct torque control. Therefore, controllers can take advantage component peculiarities, selecting role each source, accurately manage electric motor. The cell-based tested on real urban route, offering public service from/to University Calabria. simulation results different levels details: meticulous efficiency performance analysis conducted. output hydrogen consumption (approximately 0.3 kg/km) examined losses efficiencies evaluated, reaching 42.5% overall vehicle efficiency, order study flux form conclusive considerations regarding pros cons cell hybrid systems railways.
