The synchronous reactance of the direct-axis and quadrature-axis of a three-phase, 40-pole, 50 Hz, 13,8 kV, salient-pole synchronous generator is 2,38 Ω and 1,33 Ω respectively. The resistance of the star-connected stator is negligible. The load angle of the machine is 30°e and the excitation is set to induce an emf of 167%. Sketch the phasor diagram and calculate: (a) current (b) power (c) reluctance torque
