Pre-fault voltage is determined by a factor called the c-factor, which is a multiplication factor that is multiplied by the nominal p.u. voltage to arrive at a pre-fault voltage. In the IEC…
There are several ways of modelling an SVC system: Using the SVS Interface in PowerFactory: A number of standard controls for SVS are available in the global library. There, you can also find…

The injection of harmonic currents is modeled in PowerFactory using the "Harmonic Sources" object (class "TypHmcur"). Various PowerFactory elements can be configured as harmonic current sources, such…
The attached PowerFactory project contains a transmission system with prepared measurement devices ready to run a State Estimation (ComSe). The special thing in transmission system is that there are…

This example evaluates the flicker coefficients for the various operating conditions specified in Table A.1 - Annex A of the IEC/TR 61000-3-7 (Edition 2.0). Although the intention of this example is…
This example can help you understand the following: - the purpose of the commutation reactance while applying it to the HVDC-LCC element (ElmHvdclcc); nevertheless, the same procedure applies to line…

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…

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…
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…
