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 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…
For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
An example is provided attached depicting a linear and a non-linear dynamic load model.…
A synchronous motor is typically started as an induction machine while a field winding resistance is also used. The "asynchronous" motor starting of a synchronous machine implies the use of rotor…
The example shows the application of an SSSC based on a two-level converter for EMT simulation. The grid is composed of two voltage sources and three 110 kV parallel lines. The SSSC is installed at…
A modular implementation of the WECC dynamic composite load model (CMPLDW) is included as a Template in PowerFactory versions 2020, 2021, 2022 and 2023. The latest version of this Template is now…
