A synchronous generator has 4 poles and a synchronous reactance of 5 ohms. The operating frequency is 60 Hz. The stator windings are connected in Y and the voltage between the lines is Vl= 15 kV. The generator line current is 1 kA with a power factor of 0.9 (lagging). Find: a) The amplitude of the excitation voltage (induced voltage Eaf. ). b) The actual power delivered by the generator. c) The reactive power supplied by the generator.

A 50-MVA, 30-kV, three-phase synchronous generator has a synchronous reactance of 8 Ohms/phase and negligible armature resistance. The generator is delivering 50 MVA at 0.8 pf leading to an infinite bus at the rated voltage. Determine the excitation per phase E and the power angle &. Select one: O a. E = 22.78 KV and 8= 15.67 deg. O b. E = 14.115 KV and 8= 25.85 deg. O c. None of these O d. E = 13.96KV and 8= 29.74 deg. O e. E = 27.47KV and 8= 22.84 deg. Impedances are marked in perunit on a 100MVA, 100 KV base. The load at bus 2 is S2= 16MW - 132 MVAR, and the load at EN ? 1:4 4/1- TOSHIBA
