PSSE to Python and run from inside of the PSSE

edit

It is normally very easy to start PSSE-35 from python. It is no longer needed to add libraries to the system path. This will start the newest installation of PSSE-35:

import psse35
import psspy
psspy.psseinit()

Hey! you'll need to import PSSe to a python script. I'll copy an example below. you'll need to update the paths with the location of your PSSe install on your machine.

import os,sys

# Path stuff
sys.path.append(r"C:\Program Files\PTI\PSSE35\35.3\PSSPY37")
sys.path.append(r"C:\Program Files\PTI\PSSE35\35.3\PSSBIN")
sys.path.append(r"C:\Program Files\PTI\PSSE35\35.3\PSSLIB")
sys.path.append(r"C:\Program Files\PTI\PSSE35\35.3\EXAMPLE")
os.environ['PATH'] = (r"C:\Program Files\PTI\PSSE35\35.3\PSSPY37;" 
  + r"C:\Program Files\PTI\PSSE35\35.3\PSSBIN;" 
  + r"C:\Program Files\PTI\PSSE35\35.3\EXAMPLE;" + os.environ['PATH'])

import psse35
psse35.set_minor(3)

import psspy
psspy.psseinit(50)

case_file = '../input_files/case14.raw' # update this with a path to an example case
psspy.read(1, case_file)
psspy.fnsl()
