Transcribed Image Text:
A 200 MVA, 2-pole, 30 gas turbine generator is attached to a 500 KV (line-line), 60 Hz grid transmission line via an ideal step-up transformer with a turn ratio of a = 0.03. The rated line-line output voltage of the generator is 15 KV. The slope of the generator's power-frequency curve is 18 MW/Hz, and the slope of the line relating the line-neutral terminal voltage to reactive power is 15 KVAR/V. The armature winding resistance of the generator is negligible, and the synchronous reactance is XS = 0.3 2. The generator is providing 180 MVA (total 3 apparent power) to the grid at a power factor of 0.8333 lagging. [10 pts] What is the rotational speed governor setpoint of the generator, in RPM? b. [10 pts] What is the no-load terminal voltage setpoint of the generator? C. [10 pts] What is the input torque from the gas turbine (neglect mechanical losses)? a.
