Notes

  • ePHASORSIM has currently the following limitations for the import of PowerFactory models:

    • Only positive sequence simulation and positive sequence components as described in Native Library section are supported.

    • Only a subset of the PowerFactory components are supported by the import. Please refer to the Specs for DGS File Format for a full list.

    • Only dynamic controllers from the PSS/e E compatible library (v2022 or 2019) are supported. DIgSILENT or IEEE , CGMES, IEEE or other category of controllers are not supported.

  • This guide has been tested with PowerFactory version 2019 SP1 and 2023.

Note

Important Warning

Verify and ensure there is absolutely no error or warning reported in PowerFactory's Output window regarding this process.Otherwise

If errors are shown, the generated *.xml format may not be compatible with OPAL-RT’s Unified Database (UDB).
If errors are shown, make Make sure your model is fulfilling the requirements listed on this page: Specs for DGS Supported Components in DGS-XML File Format

...

.

Please note that all external references to the PowerFactory model must be internalized in the project (see step 2.)

4. ePHASORSIM Solver Configuration

  1. To use the generated XML file, PowerFactory must be selected from Input file format in the Network data tab of the Solver mask.Set the following settings in the ePHASORSIM Solver Mask
