Using Separately Excited DC Motor in Railway Vehicles Systems

Abstract

Like most road running vehicles, a railway
traction power system provides mechanical power that can be
converted into kinetic and potential energy and can be
used to overcome resistance to motion.For every successful
train traction system, there are certain general requirements
which should be met such as The capability to start and haul a
prescribed load over its specified routes whilst maintaining
the timetable and a sufficiently long service lifetime with
minimal non-availability due to maintenance and standby.
Three typical railway traction systems are used in railway
system: electric, diesel electric and hybrid. DC and AC
electric traction systems are commonly deployed in the
railway industry. A separately excited DC motor is adopted in
this paper. The electric vehicle power train system and the
components are modelled in details and all the simulation
models has been done designed and evaluated with Matlab
programming environment.
