modelTrafo3IdealBase
Base for ideal transformer, 1-phase
Extends from Ports.PortTrafo_p_n_n (Three port for 3-winding transformers).
Information
Terminology (formal).
- index 1 (term_p) "primary"
- index 2a (term_na) "secondary a"
- index 2b (term_nb) "secondary b"
Transformer ratio.
The winding ratio is determined indirectly by the choice of nominal voltages.
It may be > or < 1.
Tap changers.
For constant transformer ratio no tap changer input needed.
For variable transformer ratio tap changer input needed.
The sequence of the parameters
v_tc tc voltage levels v_tc[1], v_tc[2], v_tc[3], ...
must be defined in accordance with the input-signals of
tap index of tap voltage levels, v_tc[tap]
Set dynTC = true if tap-index changes during simulation.
