A 480-V, 50-Hz, Y -connected, six-pole synchronous generator is rated at 50 kVA at 0.85 PF lagging. It has a synchronous reactance of 1.0 per phase. Assume that this generator is connected to a steam turbine capable of supplying up to 42 kW. The friction and windage losses are 1.6 kW, and the core losses are 1.2 kW.
a) Sketch the capability curve for this generator, including the prime-mover power limit.
b) Can this generator supply a line current of 53A at 0.75 PF lagging? Why or why not?
