This is an Excel file based on the provided template file in the product. This file must have these pages:
- General
- Pins: this page can be empty
It may also include:
- Vsource
- Current Injector
Note:
- The I/O pins for PSS/e input files only support positive sequence components.
- The bus names used in Vsource and Current Injector tabs must also follow the conventions described in the table below.
The Pins tab in the Excel file is used to define the required incoming and outgoing ports as described in Pins section. Note that only positive sequence component I/O pins are supported for PSS/e that are listed in Native Library section. For each component of the system in the RAW and DYR files, ePHASORSIM automatically creates a unique internal ID. To create an incoming or outgoing pin, this ID of the component must be declared in the Pins page of the Excel file.
The convention of creating these internal IDs is based on a combination of prefixes, the bus names, and identifiers that are given in the PSS/e RAW and DYR files. The identifiers in PSS/e RAW files are one or two-character uppercase non-blank alphanumeric. The following table lists these convention:
