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 project contains the LCC-HVDC benchmark model. The project includes two study cases, one to study the load flow conditions (LoadFlow Conditions) and a second prepared to perform…

For RMS simulations the load type has to be set to 100% dynamic load, this means constant impedance Z. Additionally in the RMS dialogue of the load type the voltage dependency of P and Q can be set.…
The A-stable integration algorithm is described in the PowerFactory User Manual, Chapter "Stability and EMT Simulations", Section "Algorithm control".…
This example can help you understand the following: - the purpose of the commutation reactance while applying it to the HVDC-LCC element (ElmHvdclcc); nevertheless, the same procedure applies to line…

The idea of the initialisation is to preset the internal model signals by the results of an initial load flow.The key point is to first check for each DSL-model, which inputs/outputs are known and…
In order to create a Bode diagram you will need to use the Model Frequency Response command (ComFreqresp). This command is described within the User manual, section "Frequency Response Analysis",…
The attached project is based on the medium voltage distribution network benchmark developed by Cigré (European configuration) [1]. The MV network includes two points of connection to the upstream HV…
