Question
A 13.5kV, 18.2MVA, 0.9 power factor lagging, 50HZ, 2-pole, Y-connected synchronous
generator has a synchronous reactance of 2 2 per phase and a negligible armature resistance.
The combined core and mechanical losses are 1MW for all load conditions. The synchronous
generator is driven by a gas turbine that can supply a maximum of 20MW.
The generator is connected to a balanced Y-connected load with an impedance of 25/25°Q
per phase. Under this condition:
Draw and label the per-phase equivalent circuit of the synchronous generator with the
load. Calculate the per-phase internal generated voltage when the load is connected to
the rated terminal voltage.
(b)
Determine if the synchronous generator can safely supply the power to this load by
drawing the capability curve and checking all the power and current limits.
