Hi,

I am trying to run simple dynamic simulation from python shell using following script.


import os,sys
import csv
import pssepath

pssepath.add_pssepath()

SaveFile="YPS_CONV.sav"
SnapFile="YPS_SNP.snp"
OutFile="Test_Line.out"
path=os.getcwd();
print path

import redirect
import psspy

redirect.psse2py();

ierr= psspy.psseinit(buses=150000);

psspy.case(os.path.join(path,SaveFile))
psspy.rstr(os.path.join(path,SnapFile))
psspy.strt(0,os.path.join(path,OutFile))
print os.path.join(path,Outfile)
psspy.run(0, 1.0,10,10,10)

Whenever I run this code it works fine up to "psspy.rstr" (load snap file) and try to do something for next command and shell "Restarts" itself.

If I run same code from "psse" itself, it works fine.

I have seen many of us have used the same code and it seems it is working fine for others.

can someone please help?

Following is the log output (sorry site didn't allow me to attache the file so have to copy it here).

Change the line:

print os.path.join(path,Outfile) to

print os.path.join(path,OutFile)
