SynchronousMachineSimplified

The simplified model represents a synchronous generator as a constant internal voltage behind an impedance (Rs + jXp) as shown in the Simplified diagram.

Since internal voltage is held constant, there is no Efd input and any excitation system model will be ignored. There is also no Ifd output.

_This model should not be used for representing a real generator except, perhaps, small generators whose response is insignificant. _

The parameters used for the simplified model include:

- RotatingMachineDynamics.damping (D);

- RotatingMachineDynamics.inertia (H);

- RotatingMachineDynamics.statorLeakageReactance (used to exchange jXp for SynchronousMachineSimplified);

- RotatingMachineDynamics.statorResistance (Rs).
