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…
For load flow calculation, static analysis, the three phase voltages can only be altered by specifying the amplitude and the phase lag in the positive, negative and zero sequence system of the voltage…
Refer to the ]attached example for a measured voltage at a bus bar. The inputs of the voltage source are named U_A, U_B, U_C, as you can see in the composite model. These inputs represent the…
There are two ways to simulate the harmonic voltage distortion from the feeding grid: To model the infeed as a voltage source and entering the harmonics on the Harmonics page. To model the infeed as…
For being able to consider frequency dependent network impedances you may use the Voltage Source element (ElmVac) or the External Grid element (ElmXnet). On the Harmonics-page, frequency…
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 individual phases A, B and C of the AC voltage source (ElmVac) can be controlled in EMT and RMS simulation. For that purpose, a voltage source (ElmVac) is linked to composite model. The composite…
Attached you find an example with 3 unsymmetrical voltage sources. It is required to use 3 symmetrical voltage sources and to connect them to the load busbar using 3 single-conductor cables (phase A…
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…
