Attached you can find an example which includes four loads with a demand of 1 MW each. The way each load is modelled and connected to a three-phase system differs. Two loads are modelled as a…

Attached you can find a PowerFactory project containing several generic models for main transformers and generators.…

PowerFactory is able to calculate single-phase interruptions within the short-circuit calculation (complete method) and in the transient simulation. Another option is to connect a three phase line via…

This would be the standard procedure: Open the dialog of the line element by double-clicking on its graphic representation Click on the Sections/Line Loads button. A list with all the sections will…

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 standalone composite models running in parallel,…
In general two different options exist: 1. An explicit description of the motor driven machine (MDM) is defined. In this case a composite model connects the asynchronous machine with the load…

- EMT Simulation The model used permits the direct modification of the ignition angle (alpha). - RMS Simulation This model is slightly different, as the application of a soft starter does not allow a…
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…

A series reactor can be used to connect buses that operate at different voltage levels. A series reactor is used to model an impedance to connect the different voltage levels (220kV to 230kV). The…
