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?

Answer / k.prakashchandra

When it is in parallel with 7 other generators , its voltage and frequency(speed )are decided by the grid . hence its pf card is faulty as there no variation in shared load. Exchange the pf cards and confirm
