Extends from Buildings.Electrical.Interfaces.Source (Partial model of a generic source.).

Information

Model of a generator that produces real power P with a given phase shift phiGen.

This model must be used with Buildings.Electrical.AC.OnePhase.Sources.Grid or with a voltage source from the package Modelica.Electrical.QuasiStatic.SinglePhase.Sources. Otherwise, there will be no equation that defines the phase angle of the voltage.

The boolean flags potentialReference and definiteReference allows to select the phase angle of the generator as reference for the models connected to it. More info about these flags are available in Buildings.Electrical.AC.UsersGuide.
