• In Conditioning Mode, while utility power is present, the mtu Kinetic PowerPack stabilizes the voltage within pre-set tolerances. It provides power factor correction and protects the load from mains harmonics.
  • In Independent Mode, on utility power failure or voltage disturbance, the stored kinetic energy is retrieved and transferred to the synchronous machine, acting as a generator. This proceeds without interruption, a zero-second transfer to the critical loads.

Conditioning Mode

mtu Kinetic PowerPack protects the load

Independent Mode

mtu Kinetic PowerPack provides energy as secondary power source, without interruption

Transfer from conditioning mode to independent mode

When the transition from conditioning mode to independent mode occurs, the frequency is maintained within a narrow tolerance, the accu’s speed decreases, and then the diesel engine starts to provide power the load.

Redundant start

In the event of a diesel engine start-up failure, the electromechanical clutch will close shortly after opening QD1, and the kinetic energy of the accu will start the diesel engine. It gives the system a redundant possibility, a second guarantee to start the engine.

Mains return back to conditioning mode

- The mtu Kinetic PowerPack‚ synchronizes with the mains supply.
- The outer rotor is re-accelerated to its rated speed.
- When the rated kinetic energy is stored, QD1 closes.
- The electromagnetic clutch opens.
- The diesel engine runs at idle speed for cooling and then stops eventually.
- The system secures the critical load against an un limited number of repeated mains failures.
