Hoist RePowering Project for 4100A Shovels
The thermal capacity of the Hoist Motors was increased by replacing the existing motors with a different motor called the M22 motor. The new motor is expected to have a longer life and improved performance. The timeline and criteria for the installation was discussed. The installation and the retrofit program was successful. Good presentation and good overhead information. See PowerPoint presentation for details.
“Suncor 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.
“Static VAR Compensator”
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.
