A power generating facility has a gas turbine driven, three-phase, 100 MVA, 13.8 kV, 60 Hz, star connected synchronous generator with a synchronous impedance of 0.15 + j1.05 0/phase connected to its infinite bus. During off-peak hours, the generator's excitation voltage is set to 14.6 kV and it supplies a load current to the 13.8 kV infinite bus at unity power factor. Ignoring the armature resistance, and at unity conditions Calculate the expected load current and load angle for this condition ii. Sketch the phasor diagram for this condition iii. Calculate the power being supplied by the generator i. ii. iii.
