For the first benchmark model refer to the PowerFactory example found in the application, by clicking in the main menu on File->Examples and changing to the "Examples from Literature" tab. Refer to…
Refer to the three attached PowerFactory projects containing a tap changer and shunt control are provided. Direct control via signal: - The project "SIM TapControl nntapin.pfd" shows a tap controller…

The attached zip file includes a small project having a Python command predefined, which must be linked to the Python script included. The script will do the following tasks: - Prepare the initial…
The AC voltage source can be controlled in RMS simulation by applying different input values to signal sets (u0,f0) or (Ul0,F0Hz). The first set controls the per unit quantities, the second absolute…

It is not possible to change the voltage set point of an external grid during a simulation. The work around is to replace the external grid by an AC voltage source (ElmVac) and then use one of the…
Since version 2017 a new module for scanning the simulation is available. Attached an example how the Fault Ride Through simulation scan can be used. The project contains two study cases, in the first…
