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 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 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…
You can model the ABC flux by performing an Inverse Clarke transform on the dq0 flux signals as shown in the attached project. Double click on the Flux ABC Virtual Instrument, click Edit, double click…

In the following example the switching in of a shunt capacitor is demonstrated (via an EMT-Simulation), with focus on the resulting capacitor inrush currents. The network model comprises a 6 kV…
It is possible to represent photovoltaic (PV) systems in PowerFactory for the purpose of power system analysis. It is important to decide from the very beginning on the type of analyses being carried…
In the provided PowerFactory project, a single phase line-to-ground fault in the middle of an overhead line can be analysed using EMT simulation. The simple network model contains a 110 kV overhead…
An example is attached, where the Voltage source is controlled via a DSL block. Three different possibilities are included in the example. Import the project in PowerFactory and run an EMT Simulation.…

The objective of the attached project is to simulate and analyse the transient recovery voltage (TRV) on high voltage circuit breakers. The circuit breaker itself is modelled by means of a breaker…
Several EMT studies (transformer energisation, load rejection, ferro-resonance etc.) require a detailed model of the non-linear behaviour of the transformer iron core which is defined by its…
