- •
The dynamics of DFIM in pump-storage plants is a relatively unknown territory.
- •
The resistance of the crowbar protection has a great effect on the DFIM’s dynamics.
- •
During a fault DFIM behaves as an asynchronous machine.
- •
During transients DFIM’s power oscillates around static “P/speed” characteristic.
- •
Static “P/speed” characteristic is affected by saturation and voltage reduction.
