Equivalent circuit on diagram layer!
Test generator, transient order = 1.
Circuit data are:
  {r[1:n], r_0} = {0.0011, 0.005},    d- and q-axis
  {xsig[1:n], xsig_0} = {0.13, 0.17}, d- and q-axis
  {xm[1:n], xm_0} = {0, 1.6} d- and q-axis (no coupling terms in transient order 1)
Corresponding transient data are:
  tc_d  = {0.684058354104098} d-axis
  to_d  = {4.17178865983301}  d-axis
  xtr_d = {0.290231213872833} d-axis
  tc_q  = {0.684058354104098} q-axis
  to_q  = {4.17178865983301}  q-axis
  xtr_q = {0.290231213872833} q-axis
  v_f denotes the field voltage.
The code uses
xsig_s for xsig_0: armature leakage reactance xsig_r for xsig: rotor leakage reactances r_s for r_0: armature (stator) resistance r_r for r: rotor resistances
