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 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…
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…
Attached you can find an example which includes four loads with a demand of 1 MW each. The way each load is modelled and connected to a three-phase system differs. Two loads are…

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…
PowerFactory provides a built-in functionality to adapt the power of selected loads to result in the measured values at the beginning of a feeder. Using the attached example, the following steps…
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…
PowerFactory provides the toolbox Quasi-dynamic Simulation to calculate a set of load flow calculations considering defined time characteristics.Almost for every element parameter, characteristics can…
