 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.
