Test model for a network model for three-phase unbalanced systems with neutral cable
Extends from Modelica.Icons.Example (Icon for runnable examples).
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 cable with neutral line.
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 (480 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.
