modelTwoPortRCLine
Model of a two port DC resistance and capacity (T-model)
Extends from AixLib.Electrical.Transmission.BaseClasses.PartialTwoPortRLC.
Information
This model represents a series of two resistances and a capacitance that connect two DC interfaces. This model can be used to represent a cable in a DC grid.
The model represents the lumped resistances and capacity (T-model) as shown in the figure below.
As can be seen in the figure, the resistance R is split in two halves
and the capacitance is located in the center.
The capacitance in the center is optional and can be selected using the
boolean flag use_C = true. The model is either dynamic or static depending on the
presence of the capacitive effect.

Removed redeclaration of phase system inTerminal_nandTerminal_pas it is already declared to the be the same phase system, and it is not declared to be replaceable. This avoids a translation error in OpenModelica. -
