modelACLine_RL
Test model for a three-phase unbalanced inductive-resistive line
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example demonstrates how to use a resistive-inductive line model to connect a source to a load.
The model has three loads load_sc_1, load_sc_2,
and load_sc_3 representing short circuits R=0.
The current that flows through the load depends on the impedance of the line.
Each load is connected to the source with different configurations, but the equivalent impedance between each load and the source is the same. Since the equivalent impedances are the same, each load draw the same current.
Note:
The line model RL_3 is the same as RL_2 but it uses
dynamic phasors.
