Yes, but there must surely be somewhere a frequency control device.
The system cannot be self-sustained, just relying on the fact that each
generator is kept in sync solely by its connection to a power grid with 
energy
at 50 or 60 Hz. Somewhere something must have set that frequency at
50 or 60 Hz.
Who controls the frequency and how ?
