To simulate a load event you have to use the EvtLod. The load event works as follows:1. Incremental change Certain percentage of current value, P = P + P*dP/100 (same for Q)2. Absolute change Absolute…
A static load model is always equivalent to a constant impedance model. For modelling any different characteristic, you have to switch it over to 100 percent dynamic. A real constant PQ load model can…
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…
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…
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…
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…
