QUESTION 1 [22] A three-phase synchronous generator with negligible armature resistance has synchronous reactance Xs = 1.65 p.u. and is connected to a very large system. The terminal voltage is 1.0 p.u. and the generator is supplying to the system a current of 0.9 p.u. at 0.85 p.f. (lag). Determine: 1.1 The magnitude and angle of the internal voltage, E; (4) To determine the magnitude and angle of the internal voltage, E, we can use the equation: E = V + I*Xs Where: V = terminal voltage = 1...
