How to model a substation using node-breaker?

Hello, I am trying to model a substation that has breaker-and-half implementation. My end goal is to do some contingency testing, so I am taking the .raw file I have and making it match the breaker setup in the real substation. I am currently using "psspy.stationbuildconfig()" but it seemingly generates the nodes and connects the associated branches randomly. I have to repeat this for a few different substations so I am trying to figure out the pattern so I can repeat it. I am using PSSE35.6 and python 3.9. Thanks in advance!

Make each substation its own script. Then run a python script to run python scripts. This is the example code for one 'large' substation.

Thank you!! Definitely a brute force strategy, but it works for what I need. If applicable for others, use station_shunt_term_chng() for fixed shunts

This example is a big substation and it looks like a lot of code, which it is, but the process is pretty formulaic. You'd be surprised how fast you can get through you're typical 3-, 4-, 5-Breaker ring bus substations.
