Power Systems Python

A set of tools for calculating power system impedances, faults, pole spans, pole line stress and strain, and voltage drops.

I had uploaded an older version some time ago, then I had overhauled the program extensiviely during my time working for an electric cooperative. I thought the code had been lost but I happened to find a backup USB drive with an nearly finished version. I have added some slight modifications to the code for compatablility over the last few months with Python 3.9 and am now at a point I I am ready to upload and begin reqorking the examples.

I do also have some utilities that I had created to pull data from a Milsoft Windmil database that I may upload in the coming months. I can no longer test the milsoft code but it will be made available.

It is my goal that this will aid some smaller cooperatives and municipalities in performing routine calculations.

Basic Overview

PoleCad

1. There is an overview document titled Pole Calculator Basic which explains file structure
2. The poleLaunch function will begin the program and if the data is correct will create top view stress, strain, and guying diagrams for each study pole, a csv file will also be created containing raw data
   1. test1 and test2 scripts and folders show basic examples of the calculator
3. The spanLaunch function will create a csv file that contains span information

powerCad

1. There curently isnt documentation on the fault calculation and time coordination curve functions, I am planning on writting these up
2. The time curve coordination will display a graph and optional reference points
   1. testtcc script and foldes show a basic example of the time coordination curve
   2. Note that the ocdevdb contains the curve list database in the tcctest folder
   3. It also shows example calls to calculate some impedances and fault currents
3. The voltage drop function has an example script called vDrop
4. The impedance calculator based on csv conductor files was never completed fully and requires further development

Future Plans

1. Add additional documentation
2. Add equipment at voltage levels other then 7.2kV
3. Complete the impedance calulation functions
