A 600 KVA, 3.464 KV 3-phase star-connected 4-pole synchronous generator is operating at full load and 0.866 power factor lagging, and field current of 18 Amps. The machine has a synchronous reactance of 10 ohms and negligible armature resistance. 50 points a. Find the generator full load power angle. b. With the same prime mover torque, and field current, if the machine synchronous reactance is doubled, what will be the new machine current, power factor, and power angle
