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…
Depending on the available input data and the kind of study (e.g. steady state, RMS or EMT) different line models (Types) are required and available in PowerFactory. The following models are available…
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…
Acharacteristic is assigned by an invisible object. This object is of the class "ChaRef" and it is stored IN the object you want to apply the characteristic to. Assumed that the load is the target…
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 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…
The Task Automation command (ComTasks) enables the PowerFactory user to run a list of various tasks ranging from specific PowerFactory power system analysis calculation functions up to generic data…
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 /…
