The conditions to be satisfied for parallel operation of DC generators include matching field current, voltage regulation, and armature reaction. The field current should be matched so that the generated voltages are equal; the voltage regulation should be within specific limits; and the armature reactions should be balanced to avoid overheating and damage to the machines.

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?
