Asynchronous machine parameters

Extends from Asynchron (Asynchronous machine parameters).

Information

Equivalent circuit on diagram layer!

Specifying standard transient data, an example:

  - for first order per axis write

  xtr = {0.4}  for  xtr' = 0.4,  no xtr'', ..
  tc  = {1.3}  for   tc' = 1.3,   no tc'', ..

  - for second order per axis write

  xtr = {0.4, 0.24}  for  xtr' = 0.4,  xtr'' = 0.24
  tc  = {1.3, 0.04}  for   tc' = 1.3,   tc'' = 0.04

and analogous for higher order.

Specifying equivalent circuit data:

    xsig_r, r_r correspond to a stator-based equivalent circuit.
    The number of components of xsig_r, r_r depends on the order of the model.
    For pu-input refer to stator base value R_base.
