     "A $200$ MVA round-rotor generator is connected to an infinite bus system of nominal frequency of $50 Hz$ through a step-up transformer with reactance of $0.13 p.u.$ and a transmission line with reactance of  $0.17 p.u.$ . The generator’s transient reactance is $x'_{d} = 0.23 p.u.$ and the inertia constant is $H = 4 s$. The synchronous generator mechanical power is set to $0.6 p.u.$ and the steady-state emf $E = 1.1 p.u.$"
