You need to validate the licence. To validate the licence proceed as follow: Connect to the internet. You can verify the internet connection following these steps: - Open the Licence Manager by…
PowerFactory includes built-in devices to measure current (StaImea), voltage (StaVmea) and power (StaPqmea). Since PowerFactory version 2022, these devices calculate the instantaneous values, true RMS…
This example evaluates the flicker coefficients for the various operating conditions specified in Table A.1 - Annex A of the IEC/TR 61000-3-7 (Edition 2.0). Although the intention of this example is…
The injection of harmonic currents is modeled in PowerFactory using the "Harmonic Sources" object (class "TypHmcur"). Various PowerFactory elements can be configured as harmonic current sources, such…
The full network model might not be available for the harmonic analysis or the full model has to be reduced for performance reasons. Examples are: Harmonic Analysis for a power plant (e.g. wind farm /…
The LDC is normally used in MV/LV radial networks to control the voltage at a remote end (by measuring the load current and compensating the voltage drop). A detailed explanation of the Line Drop…
