In order to create a Bode diagram you will need to use the Model Frequency Response command (ComFreqresp). This command is described within the User manual, section "Frequency Response Analysis",…
An AC voltage source (ElmVac) can be controlled in EMT simulations by means of signals gathered from a measurement file (ElmFile) which specifies the time series for the three phase voltages. For that…

The attached script allows the direct plotting of selected signals or states from the graphical block definition. Usage is simple: Import the script (best to the projects script folder), mark the…
The individual phases of the AC voltage source (ElmVac) can be controlled in RMS/EMT simulations. For that purpose, the voltage source (ElmVac) is linked Fourier Sources (ElmFsrc) by a composite…

The time-domain response of a cable system and overhead line model can be validated based on impedance frequency sweep calculations. With the frequency sweep command your can calculate the transfer…
An example is attached, where the current source is controlled via a DSL block. Three different possibilities are included in the example.Import the project in PowerFactory and run an EMT Simulation.…
Using the measurement file to read time series will give you a simulation time referenced value. An event based shift of this curve is not possible. The attached project shows another approach on…
For lightning transient studies, the line insulators are represented by voltage-dependent switches. There are different options to model the flashover during lightning transients, such as: Voltage…
The duration of an EMT simulation depends on the complexity of the network and integration step size that is configured in the initialisation command (*.ComInc). The integration step size depends on…
In general, instantaneous values are calculated in EMT simulations. Such instantaneous values must be processed in order to calculate RMS signals, such as voltages and current. The following are two…
