The IEC 61000 sources in the harmonic load flow follows a special rule. Since no angle information in current and voltages are considered, the current divider of the first Kirchhoff's law will not…

PowerFactory has no Active Filter model within its library. In the FAQ “How do you model active harmonic filters for harmonic load flow calculation?” an example is given how to set up an active…
An external grid can have different phase impedances modelled by using a line element defined by a tower type. The tower type is configured such that the user can enter the 3x3 impedance matrix. The…

Since version 2017 a new module for scanning the simulation is available. Attached an example how the Fault Ride Through simulation scan can be used. The project contains two study cases, in the first…

For dynamic simulations, the rotor speed of a DFIG needs be initialised externally because it is not directly coupled to the grid frequency. The rotor-side converter allows the machine to operate at…

This example provides an introduction to the analysis of arc furnaces and their influence to the supplying power system. The analysis covers the identification of the injected harmonic currents, the…
This DPL script will get all asynchronous machine types (TypAsmo) which are considered by PowerFactory to be relevant for the calculation. The names of types, where the calculation fails, are reported…
