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…
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…
The idea of the initialisation is to preset the internal model signals by the results of an initial load flow.The key point is to first check for each DSL-model, which inputs/outputs are known and…
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.…
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…

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…
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 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…

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",…
Studies involving WAMS (Wide Area Measurement System) and PMU (Phase Measurement Units) are typically executed with RMS simulation as it is the faster than EMT simulation when dealing with larger…
