You know that you can do it manually in Bus spreadsheet? Select the two columns, copy and paste into Excel.

busnum100001=100001 fvolt = open('Report_Summary.csv','w') psspy.read(0,"""ABC.raw""") ierr, busva100001 = psspy.busdat(busnum100001,'PU') fvolt.write('%10i,%7.3f,\n' %(busnum100001,busva100001)) fvolt.close()

This is my code can someone tell me why I always have this error.

import os

import sys

import numpy as np

PYTHONPATH = r'C:\Program Files (x86)\PTI\PSSE33\PSSBIN'

sys.path.append(PYTHONPATH)

os.environ['PATH'] += ' ; ' + PYTHONPATH

import psspy

import excelpy

import redirect

redirect.psse2py()

psspy.read(0,r'C:\Users\Desktop\test.raw')

psspy.fnsl([1,0,0,0,1,1,-1,0])

psspy.fnsl([0,0,0,0,0,0,0,0])

ierr = psspy.psseinit( 100000 )

ierr, (a,) = psspy.abusint(string = ["NUMBER"])

print(a)

This is my error :

Move psspy.psseinit before psspy.read. You must start PSSE before using any activity!

Do what perolofl suggested if you're doing one-shot actions.

If you want to automate it Python, you could use PSS/e API's Subsystem Data Retrieval commands:

  • abusint, with the string "NUMBER".
  • abusreal, with the string "BASE".

From there, you could write some additional python script to either:

  • Write a .csv file for importing into Excel.
  • Use one of the Excel Python libraries to write directly to an Excel file.

The scripting is a little bit of work, so unless you're doing it a lot, it may be easier just to do it manually.
