the input mechanical power of a single alternator is
increased,its RPM increased but in case of an alternator
synchronised with grid its RPM does not increased with
increase of input mechanical power. why?

Answer Posted / ashwin

it because the alternator it ynchronoed with the grid & it
output it to be kept constant as per grid ( Volt, frequency ),
frequency changes as there i an change in speed
