Several things are generally worth to keep in mind when executing an EMT simulation with PowerFactory: 1. Necessity of accurate representations of line models. PowerFactory offers lumped as well as…

For PowerFactory 2021 and earlier please refer to this example and attached files. For PowerFactory 2022 and onwards, this example is not supported anymore. Instead, a much easier alternative is…
You try to connect a power or current measurement device (StaPqmea or StaImea) but you get the message: "Selected Object NodeName 'Terminal' is not a 'Cubicle'". You have to select in this case on the…

DIgSILENT developed an EMT model of a VCB based on [1] (hereafter referred to as Greenwood’s model). Greenwood’s model simulates the voltage recovering characteristic of a VCB after contact separation…
The integration method is determined by the setting “Damping factor” in the "Calculation of Initial Conditions" command dialog, page "Solver Options", as follows: - “Damping factor” = 1: trapezoidal…
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…

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 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…
