Var / PF control

Give some details, how to control the Var / power favtor control in a synchronised generator?

i think power factor is fully dependent on load ..... so if u adjust load u can easily control it. P=1.732VIcosq
cosq is power factor .
cosq=P/1.732VI.. voltage is inversely prop to power factor.. if u adjust the generated voltage ... u can control power factor .. synchronized generator is nothing but speed of rotor is equal to flux speed ...

This is done through AVR. You have two modes on which AVR works. There are droop settings etc which needs to be checked if I am right.

i dont know what is droop control in generator?

Do you have an external AVR?

yes we have an External AVR. In NGR panel they have provided a Droop and pf control CT. And what is the use of nill meter in AVR please tell

Thank u..

Do not know to which meter you are referring nill meter. There are excitation voltage and current meters on an AVR.

Check in your AVR manual if you get some help.

sorr boss. it is null meter...I have no manual for the AVR, thats only i ask u ...
