The objective of the attached project is to simulate and analyse the transient recovery voltage (TRV) on high voltage circuit breakers. The circuit breaker itself is modelled by means of a breaker…
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…

A PowerFactory 2018 (and onwards) example along with two papers is provided for your reference. An example of a PowerFactory implementation of a fast voltage controlled based method for converter…
The attached project demonstrates the behaviour of a full-scale converter based system while subjected to an islanding event. The converter is implemented in PowerFactory using a static generator…
Refer to attached project file. The project contains two IEEE 39 bus test systems connected via two long power lines between bus 29 - bus 09 and bus 23 - bus 10. The following study cases are…
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 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…

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…
