modelUnbalancedWindTurbine_N
Base model for an unbalanced wind power source with neutral cable
Extends from Buildings.Electrical.AC.ThreePhasesUnbalanced.Sources.BaseClasses.BaseUnbalancedWindTurbine (Partial model for an unbalanced wind power source).
Information
This model is a class extended by three-phase unbalanced wind turbine power sources with neutral cable connection.
The neutral cable is connected to the ground reference.
