Hello sir
This is prakash from
bangalore i have a doubt why we have to
maintain DG power factor in the range
0.78 to 0.8
Perhaps i f it is increased means what
will happen in DG
Answer Posted / k.prakashchandra
Keeping pf at 0.8 lag when running in parallel means the
terminal voltage of gen is higher than the system or busbar
voltage.But it results in higher gen & field currents which
cause unwanted heating of armature and also the field.If
you keep the pf at unity or -ve,the gen does not contribute
to system stability.The generator should also share the
reactive power of the system, which is usually
lagging.Anyway pf may be maintained at 0.9 to 0.95 lag.
