Synchronous generator synchronous reactance Xs is composed of Xs = Xa + Xl
where Xl is the armature leakage ractance can Xa is there to model the armature reactance.
Although Xl is frequency dependent (Xl = Lw, where L is the leakage inductance which is constant), is Xa also frequency dependent ? How ?
Xa is there to model the drop in terminal voltage due to demagnetizing nature of field produced by armature conductor? Unlike the Induced internal EMF (E) of the generator which is proportional to frequency, this demagnetizing field seems to be proportional to the armature current only. So, it appears to me that Xa should be independent of frequency.
But I'm not sure, so here I am to ask.
