A 100MVA synchronous generator is connected to a 25kV infinite bus through two parallel transmission lines. The synchronous reactance of the generator is 2.5Ω. Each transmission line has inductive reactance of 2Ω and 0.2Ω resistance. The generator delivers 90MVA to the infinite bus at 0.8 power factor lagging. For the above conditions, calculate: a. The terminal voltage of the generator b. The equivalent field voltage and power angle c. The real power output at the generator terminals d. The reactive...
