# Question 3 A 3-phase, Wye-connected, 6-pole, 60 Hz synchronous generator has a stator reactance of 1

Question 3 A 3-phase, Wye-connected, 6-pole, 60 Hz synchronous generator has a stator reactance of 1 , negligible stator resistance and a stator/rotor mutual coupling Lst 0.2 H. The machine operates at a power angle of 31.48 degrees with a field current of 100 A. The machine is feeding a 3-phase Wye- connected supply having line-to-neutral terminal voltage of 2.4 kVrms. (a) Find the speed of the prime mover in rad/sec (4 marks) (b) Determine the excitation voltage (6 marks) (c) Find the line current (5 marks) (d) Find the power consumed by the load and its power factor (5 marks) (e) Find the developed torque (5 marks)
