The example attached includes a measurement file drive in a 3-phase load. Import the project, save the data file loadmeas.txt to the hard disk and select this file in the measurement file object of…
In the attached example a random signal is generated using the sample and hold noise generator (ElmNoise) within a DSL model. The generated random signal is defined to change every 1/Frequency…
The slots in the standard frames are predefined slots for the different elements a synchronous machine controller may have, i.e., the voltage regulator, the power system stabilizer, etc. The names of…
Although both look very similar, there is an important difference between the Composite Model Frame and the DSL model type (block definition). The Composite Model Frame consists of slots and signals…

The order of the signals defined in a slot and in the DSL Model Type is not relevant to the model. PowerFactory doesn't assign signals by order; it uses the signal names instead. Therefore, the name…

The damping of transient phenomena during a transient simulation is due to 2 causes: Physical damping and numerical damping. - The physical damping is due to the behaviour of the modeled electrical…

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 ’Processed and aggregated results’ included within the PltDataseries. This allows calculation…
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…
