Characteristics can be easily imported using DGS (DIgSILENT Interface for GIS and SCADA). DGS Files can be based on different file formats like MS Access, EXCEL, ASCII or XML Attached is an example in…
Assuming a harmonic voltage measurement is present and needs to be converted into current injections, the following steps need to be taken: 1. Convert the measurement data from phase voltage…
Harmonic load flow calculation and frequency sweep calculations require detailed models of lines that are also representative for higher frequencies. For that purpose, overhead lines and cable systems…
The transformer impedance is mainly influenced by the series leakage inductance and copper losses for harmonic studies based on Harmonic Load Flow Calculation and Network Impedance Frequency Sweep…
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 full network model might not be available for the harmonic analysis or the full model has to be reduced for performance reasons. Examples are: Harmonic Analysis for a power plant (e.g. wind farm /…
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…

First of all it is important to mention that import means in this context "only" creating the common model and the DSL model objects. It is expected that the types (BlkDef) exist already in the…
The general line type (TypLne) is based on impedance values and can be defined with or without the neutral wire. Depending on the use case, the neutral can be modelled either explicitly (3 phases +…
Example how you can quickly read all values of the voltage and to place them in a list after Load Flow calculation has been executed. terms=app.GetCalcRelevantObjects('*.ElmTerm') ldf.Execute()…
