A lightning event can be modelled in PowerFactory in two ways: using the built-in impulse source element (ElmImpulse) - recommended approach. using a detailed, user defined DSL model. The first method…

An AC voltage source (ElmVac) can be controlled in EMT simulations by means of signals gathered from a measurement file (ElmFile) which specifies the time series for the three phase voltages. For that…

In general, instantaneous values are calculated in EMT simulations. Such instantaneous values must be processed in order to calculate RMS signals, such as voltages and current. The following are two…
In this example an IEC compliant DLL based dynamic model named "DFT analyser" is provided intended for EMT simulations. It retrieves the magnitude (i.e. peak value of sine wave) coefficient of a…

For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
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…
A simple moving average discrete time filter is provided for your reference. It can be used for both RMS and EMT type simulations. The register model (ElmReg) could be used to calculate a moving…
In order to create a Bode diagram you will need to use the Model Frequency Response command (ComFreqresp). This command is described within the User manual, section "Frequency Response Analysis",…
Refer to attached example. It contains an IBR model and a three-phase fault is simulated in both RMS and EMT. The IBR model can operate in both RMS and EMT, whereas in EMT it can be changed from an…
The general rule is that PowerFactory provides access within DSL to variables belonging to a certain network element only if they are marked correspondingly in the Variable Selection dialog, under the…
