Dear All,
Kindly note that we cant / can synchronise DG sets of
different sizes. There are some major conditions which are
not allow to synch. differrent sizes of dg sets.
assume that 500kVA and 250kVA DG Set we have to syn.
if we loaded 80% on 500kva dg set + 50kva, then 250 will
start up and syn. with 500 kva but kindly note that it will
not share only 50 kva or both will not share the load
equally. and when load will get decrease then due to hunting
effect bigger size will share more load than lower one and
cascade tripping will take place.
