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.…
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…

A balanced load which has a grounded neutral point, i.e. with the phase technology 3PH PH-E or 3PH YN, can have a zero sequence current flow. This is obvously the case, if a zero sequence voltage is…

The IEEE 13 Node Test Feeder is available as an example project within PowerFactory (File menu -> Examples... -> Tab "Examples from Literaure"). The IEEE 13 Node Test Feeder is a distribution…
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…
PowerFactory provides different load model classes. Besides the general load model (ElmLod) there are specific models for medium voltage loads (ElmLodmv) and low voltage loads (ElmLodlv). These load…
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…
