The arc voltage of the circuit-breaker can be modelled as a nonlinear resistance. Therefore we connect a resistor (series impedance)in series with the circuit-breaker. Both the real and imaginary part…
A measurement file object (ElmFile) is used for this purpose. Attached you can find a small example which displays the first 3 channels of a ComTrade file. A measurement file object (ElmFile) is…
The individual phases of the AC voltage source (ElmVac) can be controlled in RMS/EMT simulations. For that purpose, the voltage source (ElmVac) is linked Fourier Sources (ElmFsrc) by a composite…
The options available are the following: Voltage  Measurement Device and Current Measurement Device (StaVmea and StaImea). These elements implement the measurement of time-dependent data of a…
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…
The damping of transient phenomena during a transient simulation is due to 2 causes: Physical damping or numerical damping. - The physical damping is due to the behaviour of the modeled electrical…

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…
The best option is to model the TCR using a SVC model and setting the number of capacitors to zero, as shown in attached example. In order to analyze the harmonic distortion of the current…
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.…
