In the attached example a test grid is used to shown an example configuration for a FFT (Fast Fourier Transformation) element. The example includes two Composite Models one using a three phase FFT…
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…
Yes, it is possible to exchange variables between two composite models in the same way as it is done between two common models. It is only necessary to set up a frame in which the two frames are…
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…
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…
Refer to attached files. A very simple Matlab script calculates a sine wave using a parameter for amplitude and an input variable (time) from DSL. There are no theoretical restrictions in terms…
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…
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…
