YAML Mapping Files

The YAML mapping files are used during an import of an external model format (PSS/e, CYME, PowerFactory, …) to map components and their parameters to the data model of the Unified Database and subsequentially to the ePHASORSIM solver. OPAL-RT is providing the required mapping file for most of the standard components.

When importing an Functional Mock-up Unit (FMU) as a custom block into ePHASORSIM, such mapping files must be provided to map parameters from the external model to the Modelica parameters in the FMU.

To do so, a YAML mapping file needs to be provided by the user.

• This file must be placed in a sub-directory named mappings next to the Simulink model.

• The name of the file itself is irrelevant.

• The file extension must be .yaml.

• The file must follow the YAML syntax rules.

• The file must follow the structure of the provided examples.

  • A more detailed description of the file format is provided here: File Format

• The mapping file must map FMU component to the Subsystem block

• The parameter fmuModelIdentifier must be set to the name of the FMU.

• The port must be named bus0, bus1, …, busN

• The rest of the structure must be the same. Refer to I/O Pins for PSS/E Data for naming conventions.
