    Folks,

    I'd be very much appreciative if electrically minded people would be able to shed any light on the following past exam question:

    A 722 MVA, 50 Hz, 19kV, steam driven, three phase, star connected, round rotor, sychronous generator with negligible phase winding resistance has a per phase synchronous impedance of j1.3 per unit. The open circuit voltage Eo is adjusted to 1.2 per unit and the machine is connected to a set of infinite bus bars at 19kV. The input power is adjusted to give a torque angle of 20 degrees.

    Calculate the real output power and the line current supplied by the machine.
    Calculate also the reactive power supplied by the machine under these conditions.
