recordAsynchron
Asynchronous machine parameters
Extends from Asynchron3rd (Asynchronous machine 3rd order 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.
