after parallaing two generators current is shooting up in
both the generators.for ex: load is 400 kw..after paralling
and load sharing current in running gen is approx 900 amps
and incoming is 750 amps which is too high when trying
toshift the load current in incoming gen is coming more
than 1300 amps and both getting tripped and making
blackout..

Answer Posted / yuvi

This means that the phase angle of the existing generator
and the new incomming generator are not matching. You can
try the bright lamp or the dark lamp method to synk them.
There is no way in which you can directly plug in a
alternator to an active AC system.
