Answer Posted / vittal
generating station main aim is to meet the load which can
be met completlely by the mechanical units or the source of
the prime over ,which must be mention in kw.
where as the rotationg ac machines are rated in kva
because of the losses ie the iron and copper (not on pf)
mention in kva
but even the pf is also mention on the alternator which
means the generator should be operated on that load
ex: if rating of the plant is 100 then if alternator of 0.8
pf is selected the rating of the generator must be 125
