1. (20 pts.) A 3600 rpm, 60 Hz, 13.8 kV Y-connected synchronous generator has a synchronous reactance of 20 12. The generator is operating at rated voltage and speed with the internal generated voltage EA 11.5 kV and the torque angle & -15°. Neglect the armature resistance. Please find the following values: = (a) Stator current д in phasor. (b) Power factor (please indicate leading or lagging). (c) Voltage regulation of the generator. (d) Maximum output power of the generator assume the field current is unchanged.
