Problem 2. A 200 MVA, 12 kV, 0.8 lagging, four pole, three phase, Delta connected, 50 Hz synchronous generator has a synchronous reactance of X, = 0.9 p.u. and a Ra = 0.1 p.u. armature resistance. (a.) What is the speed of rotation for the generator's shaft? (b.) Determine the synchronous reactance and armature resistance in 12. (c.) What is the internal generated voltage at rated conditions, along with the power angle? (d.) If the field current is held constant, what is the maximum power possible? (e.) What are the internal generated voltage and power angle, at rated conditions, except a 0.9 lagging power factor?
