Hi,

I have been trying to open an .out file using python dyntools module, but I've getting an error: 3mw.out version is 1.47195e+19 DynChanExtract handles version 2.0 files only.

Does anyone know how to open .out file in PSS/E 34?

Thanks

Dyntools can only be used with the (old?) OUT format and not with the (new?) OUTX format. PTI said it is preparing an API to use functions within dyntools, compatible with both format types.

Within a python script, to select the (old?) OUT format for the *.OUT file, use:

psspy.set_chnfil_type(0)        #1 for OUTX format, 0 for (old) OUT format 
psspy.strt(1,myout)

@jconto -- have you heard any update on when this is expected? I just ran across this error today. Glad I found this post, surprising that PTI didn't at least change the extension of the file to indicate a change...

None. In this case, no news is bad news.

Latest PSSe v.34.4.0 has an updated version of dyntools that works with either OUT format after setting a new variable outvrsn to 0 (old format) or 1(new format) !!!

Is the PSSE v34.4.0 a premium version or a free version[50bus version]?

I use the full version. I assume that the 'free' version would be updated as well.

By default PSSE is saving .outx files instead of .out files, at least in the early version of 33.9 and 34. Change the file type in Dynamics/Simulation options. Dyntools cannot read the new extended output file format (.outx).

Please note that a file with extension .out may be in .outx format!!!

You can check the file type by opening the file in Notepad. A file in .out format starts with: FuPpHySPCD% $ while a file in .outx format starts with: FuPpHySPCD%PTI_SFL

I've been saving it as ".out" file instead of ".outx" file. It keeps giving me the same error message.

I have had this problem before. What is the file size of your .out file? Try recording fewer channels or run simulation for shorter duration. Did the simulation complete successfully? Sometimes if your network solution does not converge PSSE seems to mangle the out file.

@perolofl where in the Edit/preferences in PSSE34 can you change the file type from .outx to .out? Thanks!

Phyl: I was wrong. You can change the file type in "Dynamics>Simulation options...".
