after syncnhronistion how generator speed controlled by grid..

Answer / arjunyadav

the generator speed cannot varied ofter synchronisation
because if the speed varies then the frequency varies if we
change the speed then the over or under frequency relay
will operate and trips the circuite.

after syncnhronistion how generator speed controlled by grid..

Answer / k.prakashchandra

The grid is more powerful than the generator or the
station.The speed of any generator is decided by the grid
while synchronizing or running.3 % variation in frequency is
allowed as per IE rules.

after syncnhronistion how generator speed controlled by grid..

Answer / kj

The generator is magnetically coupled to the grid
frequency. If the fuel to the generator is increased the
generator will try to increase speed but as it is
magnetically locked to the frequency it will take more load
instead. The reverse will happen if the fuel is decreased.
Under some circumstances the magnetic coupling can be
broken. If this happens the energy from the grid will try
to drive the generator back into synch. This can cause
extensive damage to the generator and/or switchgear.
Therefore protection should be used to stop this from
happening.

my question is that....few days ago i had installed a three phase motor starter for an electric saw.the motor will run and make the hydraulic pressure which will be goes to pressure cylender by up and down lever.two number of limitswitches are also installed on cylinder for safety of motor.now when the arm of cylinder reaches to the upper or lower limit it will cut the motor's line.and motor will be stop.now wana know that what will i do that motor runs continue after the limitswitch cut it down but it shold not be made any pressure.pls answer me in brief.
