I/O Pins for PowerFactory Data

The Excel file, exclusively XLSX type, includes two tabs:

General: to set Frequency (Hz) and Power Base (MVA) for the imported power grid
Pins: to define incoming and outgoing pins described in the Pins section. Note that for PowerFactory, only positive sequence components I/O pins are supported listed in the Native Library section. ePHASORSIM automatically creates a unique internal ID for each component of the system during the generation of the *_solver.opal file. The incoming and outgoing pins for each component must be specified referring to the internal ID declared in the *_solver.opal file.

The convention for these internal IDs is based on prefixes followed by loc_name and ID (or FID in DGS v6/v7) given in the XML-DGS file (*.xml). Note that the loc_name is converted into lowercase and any space characters are ignored. The following table lists these conventions.

Please refer to the _solver.opal file directly to identify the correct component IDs.
