Answer» A 3-phase alternator has synchronous reactance, $X_{d} = 1.7241 p . u .$ and is connected to a very large system. The terminal voltage is $1.0 ∠ 0^{\circ} p . u .$ and the generator is supplying to the system a current of 0.8 p.u. at 0.9 power factor lagging. If the real power output of the generator remains constant but the excitation of the generator is increased by 20%, then the Q delivered to the bus by the generator is ____p.u. (Answer upto three decimals). 0.632
