Hi.

I'm using PSS/E version 30 and using python 2.3 to program it. Can I use a newer version of python? Is it compatible? I use the code written by JervisW. The code written by me is:

import os,sys

PSSELOCATION = r"D:\COMPONENTELOGICA\PSSE\PSSE30\PSSBIN"

sys.path.append(PSSE_LOCATION)

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

import psspy

print sys.path

Although python reports the following message:

Traceback (most recent call last):

File "D:\ISEL\TESE\zTestes_python\Testes\teste.py", line 8, in -toplevel- import psspy

ImportError: DLL load failed: The specified module could not be found.

If I write the same code but without import pssy, python prints the following paths:

['D:\ISEL\TESE\zTestespython\Testes', 'D:\COMPON~1\PYTHON2.3\Lib\idlelib', 'C:\Windows\system32\python23.zip', 'D:\COMPON~1\PYTHON2.3', 'D:\COMPONENTELOGICA\PYTHON2.3\DLLs', 'D:\COMPONENTELOGICA\PYTHON2.3\lib', 'D:\COMPONENTELOGICA\PYTHON2.3\lib\plat-win', 'D:\COMPONENTELOGICA\PYTHON2.3\lib\lib-tk', 'D:\COMPONENTELOGICA\PYTHON2.3', 'D:\COMPONENTELOGICA\PYTHON2.3\lib\site-packages', 'D:\COMPONENTELOGICA\PSSE\PSSE30\PSSBIN']

So he add the path of PSS/E. Can someone tell me what problem might be? I check for a psspy.dll and it exits. But there is no more files with the name psspy.

I'm using PSS/E version Question was relating to running PSSE v 30 and using python 2.3 to program it. Can I use with Python 2.3. Importing psspy caused a newer version of python? Is it compatible? I use the code written by JervisW. The code written by me is:missing dll error.

import os,sys

PSSE_LOCATION = r"D:\COMPONENTE_LOGICA\PSSE\PSSE30\PSSBIN"

sys.path.append(PSSE_LOCATION)

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

import psspy

print sys.path
