Information
Equivalent circuit on diagram layer!
Test generator, transient order = 2.
Transient data are:
tc_d = {0.859012450972537, 0.024700865536969} d-axis
to_d = {4.65929627144818, 0.03185596214872} d-axis
xtr_d = {0.32862524982383, 0.253031064823128} d-axis
tc_q = {0.703091060761508, 0.0226730319219496} q-axis
to_q = {4.5014019794843, 0.0318010302865584} q-axis
xtr_q = {0.27962838258275, 0.197108545894619} q-axis
Corresponding circuit data are:
{r[1:n], r_0} = {0.0011, 0.012, 0.005}, d- and q-axis
{xsig[1:n], xsig_0} = {0.13, 0.035, 0.17}, d- and q-axis
{xm[1:n], xm_0} = {0, 0.06, 1.6}, d-axis (coupling term xm[2])
{xm[1:n], xm_0} = {0, 0, 1.6}, d-axis (coupling term zero)
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
