A 80-MVA, 25-kV, three-phase synchronous generator has a synchronous reactance of 11.5 12 per phase and negligible armature resistance. It supplies a load which is connected to an infinite bus as shown in Fig. 3. E V jX, oito Fig. 3 A synchronous machine connected to infinite bus 1) Determine the magnitude of the generated emf per phase and the power angle d when the generator is supplying a 50-MW load at 0.82 power factor lagging at 95% of the rated terminal voltage. 2) Given that the generator is operating at the excitation voltage of Part (1), determine the maximum steady-state power which the machine can deliver without losing synchronism. 3) Find the armature current corresponding to the generator maximum power in Part 2.
