The single line diagram of the figure shows a generator connected through parallel transmission lines to a large metropolitan system considered as an infinite bus. The machine is delivering 0.9 p.u power, 0.866 power factor lagging. V =1.0 p.u. The transient reactance of the generator is 0.25 p.u. Determine (a) The power angle equation for the given system Draw the power angle curve Swing equation (b) (c) Vt 10.15 p.u 10.5 p.u 10.5 p.u infinite bus
