The attached example shows a single generator infinite bus bar system that goes through three swings before it gets unstable. Power Swing Blocking: The relay is measuring the time of the impedance…
Our "Diagram Layout Tool" can assist you on this.   How to do it: Open a diagram of interest on your graphics board Select Diagram Layout Tool icon from the local graphic window…
It is possible. For this task, you will have to define a new relay. This relay will represent the connection between relays of interest.   In attached project, you will find two distance relays…
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…
The modelling of LV circuit breaker releases is very similar to the modelling of HV circuit breaker relays. The main difference is that although a CT element is selected (StaCt), this element should…
To define this follow these steps: Navigate to a relay type of interest in PowerFactory DataManager  Select the icon "New Object" from the local graphic icon bar In the new open window…
By using the option “Add Label with definable Format” out of local menu bar, it is possible to insert a user defined text box in the time-overcurrent plot. Normally there is a pre-defined format…
The attached example shows how measured data in comtrade format can be displayed and replayed. After import: Please select the data folder where you stored the comtrade files (*.cfg and *.dat). Right…
Debugging a relay model can be advantageous when having trouble with the model. There are multiple cases where you have to debug a relay model. For example the relay does not trip and you want to find…
A blocking relay is setup in the example provided. The relay located at the top busbar has its first Ioc element blocked for faults downstream of the middle busbar. The second Ioc element will trip…
