PowerFactory includes built-in devices to measure current (StaImea), voltage (StaVmea) and power (StaPqmea). Since PowerFactory version 2022, these devices calculate the instantaneous values, true RMS…
The tabular reports for the contingency analysis are stored by default in the folder Database\System\Settings\Formats\Show. The DPL script called “Create” inside the tabular report is the one used to…

There are two ways how this could be done. Depending if you would like to execute dynamic or static calculation. For dynamic simulation (RMS) - Right mouse button selection on the element…
The Python support is based on provision of a Python module that can be imported into Python scripts allowing access to PowerFactory data. The scripts - independent of whether started from within…

The following models are available in PowerFactory (see attachment): Lumped PI model Distributed Constant Parameter, also known as Bergeron model Distributed Frequency Dependent Parameter Modal Domain…
The following code gets the export command from the stadycase and prepares it in such way that the data can be exported as a csv file. In this example a resultfile of a RMS-Simulation is used…

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…
This example shows a simple under frequency load shedding scheme (UFLS) in the 39 Bus New England System for the loads at buses 16, 21 and 23 in response to a disconnection of the G 06 generator.…

The following model provides an example of a long overhead line which is energised via pre-insertion resistors. The overhead line is modeled using a distributed parameters model having the geometry of…
