A generator of 200MVA rating has an inertia constant of 10MJ/MVA. With the same rotor, if the rating is changed to 400MVA, then the inertia constant (in MJ/MVA) becomes
For the transient stability of a power system.
An alternator is connected to an infinite bus delivering current of 1.2 pu at 0.85 p.f. lagging. Infinite bus voltage is (V) = 1 pu and power angle of alternator is δ = 60°. The reactance of the alternator is 1.4 pu and excitation voltage is 1.8 pu. The maximum steady state power limit will –
