modelFixedVoltage_N

Fixed voltage source with neutral cable

Extends from Buildings.Electrical.AC.ThreePhasesUnbalanced.Sources.BaseClasses.PartialSource_N (Partial model for a three-phase AC unbalanced voltage source with neutral cable).

Information

This is a constant voltage source, specifying the complex voltage by the RMS voltage and the phase shift. The model has also the neutral cable, connected to a ground reference by default.

The parameters potentialReference and definiteReference are used to define if the source model should be selected as source for the reference angles theta or not. More information about overdetermined connectors can be found in Olsson Et Al. (2008).
