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…
Refer to the attached example. In order to understand the interface of the controller with the transformer, the following information needs to be considered: Based on the fact that we consider a…
The A-stable integration algorithm is described in the PowerFactory User Manual, Chapter "Stability and EMT Simulations", Section "Algorithm control".…
For the first benchmark model refer to the PowerFactory example found in the application, by clicking in the main menu on File->Examples and changing to the "Examples from…
Refer to the three attached PowerFactory projects containing a tap changer and shunt control are provided. Direct control via signal:- The project "SIM TapControl nntapin.pfd" shows a tap…
It is possible to monitor the breaker status in a DSL model. The switches (StaSwitch) that are to be monitored must have the flag "detailed for calculation" enabled. This option is located in the…
