The best option is to model the TCR using a SVC model and setting the number of capacitors to zero, as shown in attached example. In order to analyze the harmonic distortion of the current using EMT…

A lightning event can be modelled in PowerFactory in two ways: using the built-in impulse source element (ElmImpulse) - recommended approach. using a detailed, user defined DSL model. The first method…

To define harmonic background voltages you have to link a voltage source with a DSL model or a fourier source. Refer to the example in the attached file.…
Several things are generally worth to keep in mind when executing an EMT simulation with PowerFactory: 1. Necessity of accurate representations of line models. PowerFactory offers lumped as well as…

The following models are available in PowerFactory (see attachment): Lumped PI model Distributed Constant Parameter, also known as Bergeron model Distributed Frequency Dependent Parameter Modal Domain…
Several EMT studies (transformer energisation, load rejection, ferro-resonance etc.) require a detailed model of the non-linear behaviour of the transformer iron core which is defined by its…

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 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…
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…
