The following is asked on behalf of @Fagundes I've migrated it from here: http://forum.whit.com.au/psse-help-forum/question/122/how-do-i-import-the-psspy-module-in-a-python?answer=262#post-id-262

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

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

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\\zTestes_python\\Testes', 
 'D:\\COMPON~1\\PYTHON_2.3\\Lib\\idlelib', 
 'C:\\Windows\\system32\\python23.zip',
 'D:\\COMPON~1\\PYTHON_2.3',
 'D:\\COMPONENTE_LOGICA\\PYTHON_2.3\\DLLs',
 'D:\\COMPONENTE_LOGICA\\PYTHON_2.3\\lib',
 'D:\\COMPONENTE_LOGICA\\PYTHON_2.3\\lib\\plat-win',
 'D:\\COMPONENTE_LOGICA\\PYTHON_2.3\\lib\\lib-tk',
 'D:\\COMPONENTE_LOGICA\\PYTHON_2.3',
 'D:\\COMPONENTE_LOGICA\\PYTHON_2.3\\lib\\site-packages',
 'D:\\COMPONENTE_LOGICA\\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 haven't got a copy of PSSE v 30 around to check this out. Does anyone else? Copying files from a later version of PSSE is unlikely to work because of the difference in Python version used.

I read on Stack Overflow that you can use Dependency Walker on the psspyc.pyd file in the PSSBIN folder.

It should report on the required dlls so you can find which one is missing. It might be a simple problem with the PATH set up.

Well, in my file PSSBIN there isn't any psspyc.pyd so i guess some file are missing in my PSS30. I will check it out with my friends and see if they have those files.

Well, in my file PSSBIN there isn't any psspyc.pyd so i guess some files are missing in my PSS30. I will check it out with my friends and see if they have those files. Meanwhile, i try python 2.5 with PSS32 student version. Another error appears, i run the code and the follow message appears:

"Messages for api LIST

PSS(R)E not properly initialized"

Thus anyone knows how to solve this problem?

My code was:

import os,sys

sys.path.append(r"D:\COMPONENTE_LOGICA\PTI\PSSEUniversity32\PSSBIN")

os.environ['PATH'] = (r"D:\COMPONENTE_LOGICA\PTI\PSSEUniversity32\PSSBIN"+";"
                      + os.environ['PATH'])


import psspy

import redirect

redirect.psse2py()


psspy.fdns([0,0,0,1,1,0,99,0])
