modelSimpleTransformerComplex

Transformer modell of a predefined Dy with simple efficiency modell, based on ComplexPowerPort

Extends from TransiEnt.Basics.Icons.Model (Icon for models).

Information

1. Purpose of model

Simple model of a power transformer. Losses are specified by constant parameter.

2. Level of detail, physical effects considered, and physical insight

L1E (defined in the CodingConventions) Only the ratio and efficiency of the transformer used.

3. Limits of validity

No reactance or resistance for modeling the transformer. No dynamics.

4. Interfaces

Two Complex Power Ports for modeling a two pin

5. Nomenclature

(no elements)

6. Governing Equations

U1=ratio*U2

7. Remarks for Usage

Do not use for short circuit calculation.

8. Validation

validated by Jan-Peter Heckel (jan.heckel@tuhh.de)

9. References
