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…
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…
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…
Refer to the attached project. The options shown are: Direct start with star-delta switching: Parameter i_star = 1 (Star), i_star = 0 (Delta) Additional rotor resistance: signal rradd (can…
The Matlab Simulink - PowerFactory simulation interface is described in detail in the User Manual, Chapter "Models For Dynamic Simulations", Section "Matlab Interface". A simple Simulink Model…
Check the user settings. The options for the output window allow for disabling certain parts of the text. Enable the Errors , the Warnings and/or the information option if these messages are to be…
The nominal current rating for the transformer is calculated as follows:Inom(HV) = Snom / SQRT3 / Unom(HV) * ratfacInom(LV) = Snom / SQRT3 / Unom(LV) * ratfacUnom(HV) = rated HV voltage of the…
The attached example shows how to model an ideal 3-phase transformer, representing the influence of the delta winding in addition to three single phase transformers with different short…
Only the parameters inside the frame (Sub-)Conductor are defined for sub-conductor. All other parameters (e.g. rated current) are specified per bundle. The tower type only specifies…

If you want to simulate the synchronisation of two different systems, you can model and simulate both systems as separate networks. After some seconds you can then connect them with a circuit breaker…
