New or re-power synchronous machine as condenser
Cost, maintenance, reliability, and operation performance
Well proven, industrial type of machines for lowest maintenance and reliability
Multiple smaller standard units (modules) for best availability
Salient pole design for maximum operating range and stability
Performance
Start up / Shunt down
Pony motor starting for totally controlled acceleration with no high voltage drop and with an automatic bumpless synchronization.
Controlled deceleration through re-generative breaking for short coasting down time and fast restart
Steady state (normal operation), Dynamic (disturbance)
Control system designed for remote operation and enhanced ride-through capability
Power consumption
Low machine losses and small peripherals like lubrication pumps, water circulation pumps etc
Sub-synchronous oscillation
Eliminated during start by pony motor starting
System study may be required for normal operation.
