A simple moving average discrete time filter is provided for your reference. It can be used for both RMS and EMT type simulations. The register model (ElmReg) could be used to calculate a moving…
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 project. An example of a photovoltaic (PV) system running in parallel with a synchronous generator is provided. The PV generator (Static Generator) is feeding the load. The grid…
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…
For synchronising a synchronous generator to a power network you need to consider the following: The flag spinning in isolated operation (load flow page) should be enabled. Otherwise the synchronous…
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…
Refer to the ]attached example for a measured voltage at a bus bar. The inputs of the voltage source are named U_A, U_B, U_C, as you can see in the composite model. These inputs represent the…
