IEEEG2 / GovSteam 2
Context
This governor model appears under the name GovHydroIEEE0 in the Common Information Model for Dynamics - Standard Models (2012) {% cite CIMStandardModels2012 %} and in the IEC 61970-302:2024 version {% cite IECCIMForDynamics2024 %}.
Model use, assumptions, validity domain and limitations
IEEE simplified hydro governor-turbine model. Used for mechanical-hydraulic and electrohydraulic turbine governors, with or without steam feedback
Model inputs and output
The input variables are :
| Variable | Description | Units |
|---|---|---|
| omegaPu | measured angular frequency | pu (base omegaNom) |
| omegaRefPu | reference angular frequency | pu (base omegaNom) |
| PmRefPu | reference mechanical power | pu (base PNomTurb) |
The output signal is PmPu, the mechanical power in pu (base PNomTurb).
Model parameters
