Currently certain motors are designed to run on variable
frequency drives. By reducing frequency the motor speed is
also decreased. These drives control motor voltage and
current proportional to the frequency so that motor torque
is maintained at that particular speed.

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?
