Answer / k.prakashchandra

Size , capacity do not matter ?

Answer / e.subhash

If a.C generator means

The following condition should be same before synchronizing the generator (whatever it may be it's size)
1) bus voltage and machine voltage
2) bus frequency and machine frequency
3) bus and machine phase sequence
4) phase angle

The following method is using for synchronizing.
1) dark lamp method
2) bright lamp method
3) synchroscope method

Answer / tasawar abbas suddle

When I sync. the two more than generator we must knowledge of the generator like as its frequency, phase seq, voltage magnitude & phase angel. and its capacity is also same.

if these generator capacity not same then when i start the generator will give the power to the system the other generator is small when big generator give the power to system and the other small generator will absorbed the power and it work like as motor.
and the second small generator will also absorbed power there is no benefit
