Power Generation
Stewart & Stevenson designs, engineers, manufactures, tests
and certifies power generation packages for land based and
offshore drilling operations. These energy efficient, operator
friendly and easy to service power generation packages fea-
ture quality components that ensure continuous operation in
challenging oilfield environments and engine controls for safety
shutdown and self-diagnostics.
In addition, we provide the drilling and well servicing market
with new and refurbished engines, power units and pump
packages that increase productivity, improve efficiencies
and reduce costs. Product support by certified technicians
is available wherever on the globe our customers put our
equipment into service.
Generator Synchronization Controller
The generator controller includes the engine generator regula-
tor, which controls speed and voltage of the diesel generator
sets, the backup control, synchronizing equipment and bus
feeder breakers. A motor control center controls and protects
the auxiliary equipment.
The generator control system, designed as a universal generator
set controller, operates with either 12 or 24 volt DC electronics,
at 50 or 60 Hz and at AC ratings up to 600 volts. It can be used
for diesel, natural gas, LP and gasoline engines. All generator set
parameters — oil pressure, fuel level, engine temperature, battery
voltage, AC voltage, phase, AC amperage and frequency — are
monitored on the 32-character, back-lit LCD display.
Silicone Controlled Rectifier (SCR) Systems
Stewart & Stevenson designs, builds and supplies custom
SCR systems that typically consist of a DC-2000 drive, motor
controls, respective consoles, AC generator control and
transformers. When required, the system is installed in an
environmentally controlled power control room or building.
Variable Frequency Drive (VFD) Systems
The VFD system allows the operator to control the frequency
and voltage going to an electric motor. Using a joystick control,
the operator can precisely control the speed at which the
motor is turning.
On an electric rig, an electric motor turns the drawworks.
By controlling the speed of that motor through the VFD, the
operator controls the speed at which the traveling block moves
up and down the mast. Other motors on an electric rig are
similarly controlled by the VFD. Housed separately, it may be
operated in the control cabin.
