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.…
PowerFactory fully supports all kinds of unbalanced  power system models:- 3phase, 3 wire (loads in Delta, can be unbalanced, lines can be unbalanced)- 3phase, 4 wire (neutral is modelled…
An example is provided attached depicting a linear and a non-linear dynamic load model.…
To assign a spectrum to the load element, firstly add a load type to the load element and then set the model to current source. The spectrum must be defined and assigned under the Harmonics page of…
The attached project includes a DPL script that writes a result file and then export it into a comma separated values (csv) file. The result object is defined inside the DPL command. The scaling…
The attached project includes a DPL script that writes a result file. The result object is defined inside the DPL command. The scaling factor of the loads is changed between 0 and 1, a load flow…
The voltage dependence is defined in the load type (TypLod). Therefore a load type has to be defined in a first step. In its Load Flow tab, the voltage dependence can be configured for active and…

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…
