modelTwoStateInertiaWithIdealClutch
Extends from TransiEnt.Components.Mechanical.Base.PartialMechanicalConnection (Abstract mechanical connection model used between turbine and generator (could be an Inertia element or a clutch..)).
Information
1. Purpose of model
Rigid mechanical shaft that can be used for simulation of grid inertia and can be disconnected by input value 'isRunning'.
2. Level of detail, physical effects considered, and physical insight
(no remarks)
3. Limits of validity
This model contains moment of inertia statistics. It sends the moment of inertia specified by parameter J to the statistics component if it is connected, i.e. if isRunning=true
4. Interfaces
mpp_a: mechanical power port
mpp_b: mechanical power port
isRunning: BooleanInput
5. Nomenclature
(no elements)
6. Governing Equations
(no equations)
7. Remarks for Usage
