The A-stable integration algorithm is described in the PowerFactory User Manual, Chapter "Stability and EMT Simulations", Section "Algorithm control".…
The Example on arcing voltage of the Circuit-Breaker, in an EMT simulation, can be found in the Switching Transients example within PowerFactory, study case 08 Short-Circuit CB SF6 Arcing Model, with…
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…
An example for a DC/DC converter (using ElmDcdc element) is provided attached. The DC/DC converter supports either buck or boost configurations. The buck converter can be chosen by setting the value…
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",…
Please refer to the attached files, containing an EMT-Simulation example of a three-phase three-level neutral point clamped (3L-NPC) converter. The converter controller is available in Matlab Simulink…
The short circuit trace feature in DIgSILENT PowerFactory is designed to provide a more accurate representation of protection device tripping sequences, tripping times, and fault clearance times than…

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…
