PSAP File Format
May 20, 1993
The PECO PSAP File Format is fully described in the _PJM Power System
Analysis Package Use's Guide_, available from the Philadelphia
Electric Company. The following is a rough description of the
most important parts of the format.
A PSAP data file is divided into sections by code cards. The code is
in the first three columns. There are something like 60 codes, of
which only four are described in this document.
The 1 code indicates that the next card is the case title. Only one
title is allowed per case.
The 4 card indicates that line data follows. The line data ends with
a 9999 card.
The 5 card indicates that bus data follows. The bus data ends with
a 9999 card.
The 15 card indicates that area interchange data follows. The data ends with
a 9999 card.
