The synchronous generator below delivers $0\mathrm{.}8$ per$-$unit real power at $1\mathrm{.}05$ per$-$unit terminal voltage. Determine $($a$)$ the generator internal voltage; and $($b$)$ an equation for the electrical power delivered by the generator versus power angle $8.($c$)$ If a fault occurs on point F$,$ close to Bus$-1,$ determine the equation for the electrical power delivered by the generator versus power angle $8.($d$)$ if the fault is cleared by opening breakers B$13$ and B$22,$ determine the equation for the electrical power delivered by the generator versus power angle $8.$
