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",…
The AC voltage source can be controlled in EMT simulations based on a measurement file (ElmFile) of the three phases A, B and C. For that purpose, a voltage source (ElmVac) is linked to the…
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…
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…
This example provides an introduction to the analysis of arc furnaces and their influence to the supplying power system. The analysis covers the identification of the injected harmonic currents, the…
It is possible to use the results of the Prony Analysis in a DSL model in order to generate a synthetic time domain curve as a summation of all resulting individual components. The generated curve can…
