Additional Notes

A. Working with .psout files

A.0 Introduction

The .psout format is a modern, proprietary binary format introduced in PSCAD V5 for storing EMTDC simulation data. It replaces legacy text-based .out files, offering significantly smaller file sizes, faster read/write speeds, and the ability to store multiple, hierarchical simulation runs (including sequential and parallel results) in a single file

A.1 PSOUT Reader

.psout files can be viewed from within PSCAD using the PSOUT Reader

A.2 Enerplot

MHI also has a separate tool, Enerplot that can be used not only for plotting .psout files, but also to perform post processing of data using e.g. Python mhi.enerplot library

A.3 MTB and mhi-psout libraries

The MTB Plotter makes use of the "low level" mhi-psout Python library provides "high level" library or function, process_psout.py to process and plot .psout files a little bit easier.

These functions are

• getPsoutSignal use by getPsoutSignals below
• getPsoutSignals to extract a list of signals as a Pandas DataFrame
• findPsoutSignalPath find the signal path name or names of a specified signal name

Two scripts are also provided,

• psout_to_csv to extract all the signals listed in figureSetup.csv from a .psout file, and convert it to human readable .csv format
• list_psout_signals to list all signal, and their relative signal path, in a .psout file
