| Abstract |
The paper deals with the control strategy for the
prototype AC tram drive designed for modernization of
existing trams in Poland. The basis of the drive are vectorcontrolled
induction motors sourced from voltage inverters.
Motor shaft speed sensing enables torque and rotor flux
indirect control in stator-current oriented co-ordinates
system. In the paper the block scheme of such a control is
given and distinct work-states of the drive during the tram
driving by motorman are described. Traction properties of
the drive were checked during street tests of the tram.
During tests the behavior of the drive in dynamic states
while accelerating and electromagnetic braking of the tram
was especially observed. Results of these observations at
different tram drive operation conditions in a form of
torque and speed transients were enclosed. |
