A 100-MVA, 14.4-kV, 0.8-PF-lagging, 50-Hz, two-pole, Y-connected synchronous generator has a per-unit synchronous reactance of 1.1 and a per-unit armature resistance of 0.011. a.
A 100-MVA, 14.4-kV, 0.8-PF-lagging, 50-Hz, two-pole, Y-connected synchronous generator has a per-unit synchronous reactance of 1.1 and a per-unit armature resistance of 0.011. a. What are its synchronous reactance and armature resistance in ohms? b. What is the magnitude of the internal generated voltage EA at the rated condition? What is its torque angle 8 at these condition? c. Ignoring losses in this generator, what torque must be applied to its shaft by the prime mover at full load?
