The values of Xd and Xq are determined by applying a balance reduced external voltage (say, V volts) to an unexcited machine at a speed a little less than the synchronous speed (the slip being less than 1%). Connection diagram is shown in circuit diagram. Due to voltage V applied to the stator terminal a current I will flow causing a stator mmf.
7/27/2020 · The method used to determine X q and X d , the direct and quadrature axis reactance is called slip test. In an alternatore we apply excitation to the field winding and voltage gets induced in.
