presentation for details.
Expansion Project – Millennium Extraction Plant”
Kent made a
PowerPoint presentation on the New Extraction Plant at Suncor’s
Millennium Project. Some of the highlights was the high voltage
line up with Tertiary Wound Transformer to reduce the high voltage
lineup. The elimination the pump gearboxes by using a 16 pole
motor and running at 50Hz. The use of Device Net to eliminate
control wiring and reduce the commissioning time. Even Start and
Stop Signals are sent on communication link. There are no output
contractors for each motor (5 motors @ 2500 Hp) are fed from one VFD.
There is only temperature and current monitoring via a Multilin 369.
Gary made a
presentation on the under voltage problem at Black Thunder Mine.
The problem occurred when a Marion 8750 Dragline was added to the 69KV
system at the Mine. The system used skids, one with three 3500 Hp
synchronous motors and the second with two (2) 3000 Hp synchronous
motors to develop the KVAR of reactance needed to keep the voltage
within +2% to –4%. See paper for details.

was made by Woody Hause on the advancement made in P&H’s shovels.
These machines have moved from analogue to microprocessor controlled
machines. Temperature and pressure switches have been replaced
with transmitters so more information is available. The direction
will be to collect more and more information however the methodology of
handling this information has not been determined.
