Answer / jignesh patel
50 Hz.
stator winding and rotor winding has rotating field so it
has 50Hz freq.
There is a commutator which is converted ac voltage in to
dc.

Answer / ashok
p=4;
ns=1500;
we know that
ns=120f/p;
f=ns*p/120;
f=50hz

Answer / jenjen
The question is not clear. It does not clearly mention whihc
frequency it refers to.
If we consider the output d/c voltage, its frequency should
be zero; however, the frequency of the generated voltage in
the armature will be:
1500*4
f= ------ Hz = 50Hz.
120

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 onbserved 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?
