-0 marks
An alternator is connected to an infinite bus as shown in fig, It delivers 1.0p.u. current at 0.8pf lagging at
V=1.0 p.u. The reactance of the alternator is 1.2p.u. Determine the active power output and the steady state power limit. Keeping the active power fixed, if the excitation is reduced, find the critical excitation corresponding to operation at stability limit.
