Hi ! I am Milind. I have two queries regarding Generators and PF.

1. Does a captive power plant, consisting of several generators ( GTG or DG ) in parallel, require power
factor correction ? I mean , if the plant PF is around 0.8, that should be OK, is it not ? Is there any
overwhelming need to apply PF capacitors to improve it further ?

2. Suppose , if above CPP is runing in parallel with grid supply, can I control generator excitation so that
almost all the kVARs required by the load are supplied by the generators and I do not import any kVARs
from the grid thereby maintaining grid PF to almost unity ? This way, I do not require any capcitors and
I do not pay any penalty due to poor PF of the grid.

Thanks a lot and regards,
