In some special cases values of element parameters, e.g. the base apparent power, can be transferred from the element, e.g. synchronous machine, to the control models so it is not necessary to insert…

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…

Refer to the attached Digexdyn_Description_and_Example.zip. In PowerFactory the digexdyn interface allows for linking discrete-time models in RMS or EMT simulations: This interface can be used for…

In PowerFactory, the digexfun interface allows for continuous-time as well as discrete time models to be linked into RMS or EMT simulations: With this option you can define your own user defined DSL…

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…
