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…
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…
Attached are two projects, one in English, one in German, with an EMT to RMS current and voltage signal converter implemented as a DSL model, which converts instantaneous currents and voltages…
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 following model provides an example of a long overhead line which is energised via pre-insertion resistors. The overhead line is modeled using a distributed parameters model having the geometry of…
You can model the ABC flux by performing an Inverse Clarke transform on the dq0 flux signals as shown in the attached project. Double click on the Flux ABC Virtual Instrument, click Edit, double click…
In the following example the switching in of a shunt capacitor is demonstrated (via an EMT-Simulation), with focus on the resulting capacitor inrush currents. The network model comprises a 6 kV…
In the provided PowerFactory project, a single phase line-to-ground fault in the middle of an overhead line can be analysed using EMT simulation. The simple network model contains a 110 kV overhead…
