Error reading RAW file #126

Closed thomsonian2023 closed 2 years ago

thomsonian2023 commented 2 years ago

My code is:

fn = 'X:\z2.RAW' mpc = psse2mpc(fn); %%%%%% Converts PSSE/RAW File to MATPOWER Case

I am using Windows OS, Matpower 7.1 and Octave 6.2.0. I get the following error:

Splitting into individual lines ...................... 44 lines read ... done. Analyzing sections ..................................... 15 sections ... done. Attempting to determine PSS/E revision from content. Parsing case identification data ......... unknown rev, using rev 23 ... done. Parsing 3 lines of bus data .......................................error: cellfun: all values must be scalars when UniformOutput = true error: called from psse_parse_section at line 209 column 32 psse_parse at line 155 column 23 psse2mpc at line 71 column 18 shift_factor at line 4 column 5

I am using the following RAW file. Please note that my real life RAW file is much larger and is impossible to paste here. So, I have deleted intermediate lines from the RAW file. I get the same error when I am using either the full or abridged RAW file.

My best guess is that the text encoding of the RAW file is preventing MATPOWER from correctly detecting the PSS/E version automatically. It may work if you specify it as version 30 explicitly, like this ...

mpc = psse2mpc(fn, 0, 30);

And, if you like, you can send me the RAW file by direct e-mail and I'll see if I can confirm my guess and possibly make psse2mpc more robust to different text encodings.

Yes that is what the problem was.
