why d.c. supply is given to the primary side of generator?
Answer Posted / austin kpoto
Derived from a closed loop system from alternator, when
exciter rotate rectifer induce dc voltage. Exciter diode
convert dc current from diode to rotor main armuture to
produce magnetic field to the primary side of the
alternator.Poles turns produce minus and plus sign from
main armature than alternator send dc current to AVR.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
