This is part of a problem of my past examination in Electric Machines. I don't know how to solve it yet.
A salient pole synchronous generator \$ (X_q < X_d) \$ has a connected load at rated voltage. If the synchronous generator, operating with a voltage regulation zero, and a voltage drop in the resistance of armor 0.05pu (when the magnitude of the armature current is minimal), determine:
a) Power factor load.
b) The load angle \$ \delta \$ of the synchronous generator.
I appreciate your help.

The question has a flawed premise. If there is a non zero voltage drop across the armature resistance, then the generator cannot have zero voltage regulation, since the no load voltage at the terminals will exceed the full load voltage by the aforementioned voltage drop.
