Answer Posted / 7anoter4
The synchronous a.c. generator rpm[rotations per minute]
depends on the mechanical drive rated rpm –Diesel Motor
could be high speed –for 60 Hz systems up to 1800 [I did
not see 3600] and the lower limit may be 100-150 rpm.Low
speed D.G. consume per kwh is lower so for 40 years will be
a huge advantage.
The dimensions [and weight] of the motor-and of the
generator too-decrease as the speed increase [and the price
also].The turbo-generator is 2 poles generator usually as
this is the minimum equipment and installation cost.
