PSSE version 36. Saving a .raw. Selecting "output bus names" blows up the .raw file.

I don't know where you report this stuff.

If you save a "Power flow raw data" and select "Output bus names", you create a .raw file that cannot be loaded as it outputs the extended bus ID ( name voltage) as the I field data in the generator data, branch data etc. So when you load the file you get the buses and nothing else as the load function doesn't seem to support I being given as the extended bus name.

fix. Don't select "output bus names"

You are right. There seems to be a severe bug in PSSE nowadays. I haven't used the "output bus names" option this century, but it doesn't work in rev 35 and 36.

Should be reported to PTI.

Update:

I asked PTI and they gave the answer:

Open the raw data file with File - Import - Power Flow RAW Options...

In a script, use API read with numnam=1, e.g.

psspy.read(1,r"""savnw-names.raw""")
