A 3-phase, 722 MVA, 3600 rpm, 19kV, 60 Hz steam-turbine generator has

A 3-phase, 722 MVA, 3600 rpm, 19kV, 60 Hz steam-turbine generator has a synchronous reactance of 2 ohm. The excitation voltage Ea is adjusted to 22.8 kV when the machine is connected to an infinite bus of 19 kV. If the power delivered by the generator is 108.3 MW, determine the torque angle 8 (neglect all losses).
