For correcting PF KVAr is introduced, thus formula
pf=cos A is significant
there you should have a desired PF. If for example you need
a power factor of .90 to maintain for a 30kVAR the watts
that would come will be:
A=arccos .90
A= 25.84
WATTs= KVAR/tan 25.84
= 62500 watts approx.
remember that for PF correnction it is the KVAR that is in
need of computation and not the watts so the question would
rather be, how much capacitor kVAR you need to correct the
power factor.
