Buildings.Electrical.AC.OnePhase.Lines.Examples.ACLine
Test model for a single phase line that uses commercial cable information
Information
This example demonstrates how to use a line model to connect a source to a load that uses commercial cable information.
The model has four different loads. The load sc_load represents
a short circuit R=0. The current that flows through the load depends
on the impedance of the line.
The remaining three loads R1, R2, and R3
are resistive loads. Each load is connected to the source with different configurations,
however the equivalent impedance between each load and the source is the same.
Since the equivalent impedances are the same, each load draws the same current.

Buildings.Electrical.AC.OnePhase.Lines.Examples.ACLine_L
Test model for a single phase inductive line
Information
This example demonstrates how to use a purely inductive line model to connect a source to a load.
The model has four different loads. The load sc_load represents
a short circuit R=0. The current that flows through the load depends
on the inductance of the line.
The remaining three loads R1, R2, and R3
are resistive loads. Each load is connected to the source with different configurations,
however 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.

Buildings.Electrical.AC.OnePhase.Lines.Examples.ACLine_R
Test model for a single phase resistive line
Information
This example demonstrates how to use a resistive line model to connect a source to a load.
The model has four different loads. The load sc_load represents
a short circuit R=0. The current that flows through the load depends
on the resistance of the line.
The remaining three loads R1, R2, and R3
are resistive loads. Each load is connected to the source with different configurations,
however the equivalent resistance between each load and the source is the same.
Since the equivalent resistances are the same, each load draw the same current.

Buildings.Electrical.AC.OnePhase.Lines.Examples.ACLine_RL
Test model for a single phase inductive-resistive line
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, however 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.

Buildings.Electrical.AC.OnePhase.Lines.Examples.ACSimpleGrid
Test model for a network model
Information
This example demonstrates how to use a network model to connect a source to a load. In this simple case the network has two nodes that are connected by a commercial line cable.
At the beginning of the simulation the load consumes power while at the and it produces power. The voltage at the load at the beginning is lower than the nominal RMS voltage (120 V) while at the end of the simulation it is higher. The voltage drop and increase are due to the presence of the cable between the source and the load.
The network uses cables of the type LowVoltageCable.Cu35 with
a length of 200 m.
The picture below describes the grid topology.
