Hi, could someone explain which file type I should use to save my project? The only difference I know is that the .raw file can be opened with Notepad. Also, which file type is more reliable?
It's just a style preference — I prefer using .sav because I can have both the direct sequence data (raw) and the homopolar sequence data (seq) in a single file.
If you are doing short circuit simulation, sav is preferred since it retains the sequence data. If you are doing power flow and dynamic simulations, sav or raw is okay.
.sav format is binary format and cannot be read by any other software. This format will have backward compatibility. If you are exchanging files with same version, should not have any issue and should prefer .sav format. However, if you intend to exchange data with other lower version of PSS/E or to other software, .raw format should be used. When using .raw format, sequence data should be transferred separately using .seq file format.
