Answer to Question #117809 in Electrical Engineering for Sachin Kumar

Question

A salient –pole synchronous generator has the following per-unit parameters; Xd = 1.00, Xq=
0.60, ra= 0.02Ω. If the generator is delivering rated KVA at rated voltage and at 0.8 p.f leading,
compute the power angle and the excitation e.m.f. Draw the phasor diagram also.

Answer 1

As per the given in the question,

Power angle=?

Excitation emf=?

We know that

and

From (i) and (ii)

But here the value of I is not given in the question, so it can not be determined
