1. Purpose of model
Subransient model of a synchronous machine with two-Axis description and losses. Mechanical connection is stiff.
2. Level of detail, physical effects considered, and physical insight
L4E - model with circuit description. Voltage, active and reactive power are linked together by equations.
- Mechanical connection is stiff
3. Limits of validity
magnetical behaviour simplified
4. Interfaces
epp (ComplexPowerPort)
Mechanical power port mpp
Modelica RealInput: electric potential in [V]
5. Nomenclature
(no elements)
6. Governing Equations
(no equations)
7. Remarks for Usage
Only use machines of the class together in one simulation
Model for short time characteristics 100 ms - 1 s
Set IsSlack to true for slack-bus version
8. Validation
