The attached example provides a simple network where one three phase static generator (converter) is directly being controlled via DSL to set the output active and reactive power (constant power…
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.…

A PowerFactory 2018 (and onwards) example along with two papers is provided for your reference. An example of a PowerFactory implementation of a fast voltage controlled based method for converter…
The attached project demonstrates the behaviour of a full-scale converter based system while subjected to an islanding event. The converter is implemented in PowerFactory using a static generator…
The static generator allows to control the negative sequence currents via the input signals i2d_ref and i2q_ref. Internally is the cosref, sinref signal used for the transformation (which is typically…
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",…
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…

The attached script allows the direct plotting of selected signals or states from the graphical block definition. Usage is simple: Import the script (best to the projects script folder), mark the…
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…
DSL (DIgSILENT Simulation Language) is a very powerful possibility for modelling time continuous controls and processes. But modelling discrete controls rises some problems. There is on one hand the…
