We have 3 Gensets 1.500kva,2.380kva,3.250kva How can we
connect in common busbar&we have variable load.

Answer / vishvesh
yes, we can connect this three generators in one busbar,
after fulflling following conditions.
1.voltage should be same.
2.frequency should be same.
3.phase sequence should be same.
after shynchronizing of all three outputs, we can
connect it to the common busbas.

we have to synchronise 3 dg for busbar connection.basic
conditions r
1.freq of all dg should be same.
2.phase seq shold be same.

Answer / milinda4p
to connect 2 or more generators to a common bus those
generators should be synchronised.it means
1. frequency should be same (every generator should operate
in same frequency)
2.voltage magnitudes should be same at each bus (i:e if the
generators have different rated voltage outputs correct
transformers should be used to get the same voltages at the bus)
but the POWER RATING is not going to cause any problem for
synchronizing
But in supplying a load after connecting it is important to
adjust the power supplied according to the load.( should
maintain the frequency of the system in constant value. if
not the rotor speeds of the generators should go up or down
causing and destruction or stopping of generators )

Answer / n rajesh
No,because the following points should be taken,
1.Phase sequence should be same.
2.voltages should be the same.
3.Frequency should be same.
4.Power rating should be same.
