A three-phase fault occurs on the system of Problem 11.6 at the sending end of the Transmission lines. The fault occurs through an impedance of 0.082 per unit. Assume the generator excitation voltage remains constant at E0= 1:25 per unit. Obtain the swing equation during the fault. j0.358 00000 10.40 V j0.082 The generator shown in figure delivering power to an infinite bus. Take V=1.1 p.u, and X, = 0.25 p.u. Find the maximum power that can be transferred when the system is healthy j0.1 p.u j 0.5 p.u Pm = 1.0 p.u 0+3 Vt j0.5 p.u infinite bus V=1 p.u
