Problem 9.5 In the per phase equaivalent circuit of Figure 9.10b, assume Rs = 0 and Xs =1.2 pu. The terminal voltage Va= 1 Ð 0 pu and Ia = 1 Ð - pi / 6 pu. Calculate Eaf and draw a phasor diagram similar to Figure 9.10a. (Answer this question) In Problem 9.5, with Eaf kept constant at the magnitude calculated and Va = 1 pu, calculate the maximum power in per unit that this machine can supply.
