2. A 3 phase, star connected alternator supplies a load of 10

2. A 3 phase, star connected alternator supplies a load of 10 MW at a power factor 0.90 lagging and at 11 kV (terminal voltage). Its armature resistance is 0.10 ohm per phase and synchronous reactance is 0.66 ohm per phase. Calculate the line value of emf generated. Also calculate the voltage regulation.
