a)draw the phasor diagram for this operating condition, taking
vt as a reference and determine the phasors ef and ef' en(pu)
b)draw a clear and orderly scheme of the operation chart of this
generator, indicating what each limit corresponds to and determine
the coordinates (P:Q) of a theoretical limit point of permanent
stability, if the field current of the question to it keeps

the point of the theoretical limit of permanent stability
calculated in question b
