PySV

IEC 61850 SV (Sampled Values) publisher/subscriber in Python.

Requirements

Ubuntu 20.04.

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install -y python3.10-venv

Quickstart

pysv should be run as sudo, it also expects an interface name, e.g., lo, which can be changed in the .env file.

git clone https://github.com/arthurazs/pysv
cd pysv
python3.10 -m venv .venv
. .venv/bin/activate

pip install .[async]
sudo .venv/bin/python -m pysv -ap  # async publisher
sudo .venv/bin/python -m pysv -as  # async subscriber
sudo .venv/bin/python -m pysv -debug # publisher in C
# sudo nice -n -20 chrt --fifo 99 .venv/bin/python -m pysv -debug  # minimum niceness, maximum priority
# sudo PYSV_INTERFACE="lo" nice -n -20 .venv/bin/python -m pysv -debug

Optional quickstart

Instead of using the default file specified in the .env file, you can change it through the command line interface:

sudo .venv/bin/python -m pysv -ap path/to/another_file.csv

TODO

• Fix ruff issues
• Use logging instead of print
• Make the pub/sub sync/async modules customizable
• Write unit tests
