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…
PowerFactory is using the rated power of the turbine as an additional input parameter to the turbine model and converts the turbine output (in turbine-p.u.) to synchronous machine p.u. at the output…
Import:DXF files can be used directly as background file for single line diagrams. Open the Graphic Layers dialog and switch to the Configuration page. Select the Background Layer, as Background type…

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…

In the attached example the output power of a single phase load is controlled via an external file element (ElmFile). Import the project, save the text file to the hard disk and select this file in…
You will need to perform an EMT-type simulation for this purpose. To replicate the fault on the cable insulation, the cable must be explictly divided in two sections at the point where the faulty…
There are two possibilities to work with user defined variables in a dynamic simulation: Using the option ’User Defined Signal’ included within the PltDataseries. This allows calculation of additional…
- EMT SimulationThe model used permits the direct modification of the ignition angle (alpha).- RMS SimulationThis model is slightly different, as the application of a soft starter does not allow a…
In the attached example a ramp modeled in DSL is used to reduce the turbine power pt from its initial value to zero. You also may use a similar block structure to impose a ramp on any other machine…

In the example attached, a Register and a Sample and Hold are included within the model to show their behave. The Sample and Hold stores it's sampled input signal at the output until the next rising…
