Working a lot with PowerFactory can lead sometimes to quite large result objects which occupy space on the hard disc. The attached Python script can list for you the total size of each project to help…
There are various possibilities to "bond" the sheath / metallic screen (MSC). The bonding corresponds to the earthing of the sheath / MSC. There are different bonding configurations for cables:  …
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 ferroresonance phenomena is a non-linear series resonance that may result in transient currents of high amplitude and high harmonic content. For medium voltage networks the following system…
The attached project shows the energisation of the electrical grid and the active power load pick up with the voltage source converter (VSC) in EMT simulation. The DC capacitor is charged through a…
Variable resistances can be modelled with the ElmSind. The grounding impedance represents a single phase model. Thus, the ElmSind is modelled as single phase element. The single Rin of the ElmSind is…
In an EMT simulation, the result variables are recorded as instantaneous values. In order to record RMS signals such as voltages and current, the instantaneous have to be converted to RMS values. The…
Using the measurement file to read time series will give you a simulation time referenced value. An event based shift of this curve is not possible. The attached project shows another approach on…
An example is attached, where the current 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.…
By using the option “Add Label with definable Format” out of local menu bar, it is possible to insert a user defined text box in the time-overcurrent plot. Normally there is a pre-defined format…
