modelTwoPortRLC
Model of an RLC element with two electrical ports
Extends from BuildingSystems.Electrical.Transmission.BaseClasses.PartialTwoPortRLC.
Information
This model represents a series of two resistive-inductive impedances and a capacitance that connects two AC single phase interfaces. This model can be used to represent a cable in a AC grid.
The model represents the lumped resistances and capacity, as a T-model, as shown in the figure below.
As can be seen in the figure, the resistance R and the inductance L are split in two halves
and the capacitance is located in the center.
The capacitance in the center is optional. If it is not present, set the
parameter C=0.
The model is either dynamic or static depending on the
presence of the capacitive effect.
