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 element Power System Stabilizer (ElmPss), etc. The names of the…
Although both look very similar, there is an important difference between the frame and the block diagram. The frame does consist of slots and signals connecting them. In the slots only the inputs and…

The order of the signals defined in a slot and block definition is not relevant for the model. PowerFactory doesn't assign the signals by order, but it does it using the names. Therefore the name is…

The damping of transient phenomena during a transient simulation is due to 2 causes: Physical damping or 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 ’User Defined Signal’ included within the PltDataseries. This allows calculation of additional…
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…
