Information

These examples illustrate the connection between different ways of specifying a machine.
In particular they show the calculation of

• impedance matrix from transient data
• impedance matrix from equivalent circuit
• transient data from equivalent circuit
• equivalent circuit from transient data

The parameter values are chosen in such a way, that the circuit-data
(see 'Diagram layer' of the examples)

  r_r[1:n], r_s} and {xsig_r[1:n], xsig_s}

For machines with field-winding (synchronous), d- and q-axis differ, if n > 1

  xm[2:n] > 0, coupling terms exist in d-axis
  xm[2:n] = 0, no coupling terms in q-axis
