The internal generated voltage ea of a 2-pole d-connected, Ask an Expert

Engineering

The internal generated voltage E_A of a 2-pole, D-connected, 60 Hz, three phase synchronous
generator is 14.4 kV, and the terminal voltage V_T is 12.8 kV. The synchronous reactance of this machine is 4 W, and the armature resistance can be ignored.

(a) If the torque angle of the generator δ = 18°, how much power is being supplied by this generator at the current time?

(b) What is the power factor of the generator at this time?

(d) Ignoring losses in this generator, what torque must be applied to its shaft by the prime mover at these conditions?
