How can I write a result file using a DPL script?

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…

How can I export a result file using a DPL script?

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…

How do I model a load containing harmonic components based on its spectrum?

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…

How can different balanced and unbalanced loads be modelled?

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…

How can I model voltage dependence of loads and consider it in the load flow calculation?

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…

How can I simulate a load event?

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…

How do I model correctly the load behaviour for dynamic simulations?

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…

How can I performe a load scaling?

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…

How can I control the power of a 3-phase load in a dynamic simulation using an external file?

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…

How do I calculate loads with time-dependent characteristics?

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…
