Answer / ram

Yes,Direction of Power flow depends upon the potential
difference.if bus voltage is greater than the generator
voltage ,there will a reverser flow.

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?
