Hello, i am using python script for running multiple dynamic simulation. For the cases where plb file is used i am getting playback model file not found error. .plb file is in the same location where dyr files are placed. Other simulation in the loop is running fine where plb is not used. For dyr files with plb as gives an warning in PSSE as file in use OpnApplFil/OPENSEA
My practices when using playback model:
Not sure if this will help in your case, but here is what I discovered:
When I was running the .dyr through the gui I could have the PLBVFU1 file declared like this:
BusNr 'PLBVFU1' machID 1 1 'PLBFNAME' Ubase Fbase 0 0 /
However, when I ran it in a script I would receive the error that you had. In order to solve that and make the file discoverable, I needed to declare the model like this:
BusNr 'USRMDL' machID 'PLBVFU1' 1 1 3 4 3 6 1 1 'PLBFNAME' Ubase Fbase 0 0 /
Also, I have my scripts in a separate directory from my dynamics file. It is necessary that the PLB file be in the working directory (e.g. the directory where your script is ran from).
When running dynamic simulation through Python scripts, the Playback model (.plb) file needs to be in the same folder as the Python script. (.Sav) & (.Dyr) files can be anywhere as their path can be constructed using Python. As the (.plb) path can not be built it should be in the working folder. The working folder is where your script is kept not where the dyr or sav file is stored
Can you paste the full error message? Is it a file not found error, or a file in use error?
One idea, try reducing the plb file name to just 2 characters. This was required in v33, and I don't think v34 has that restriction, but it's worth trying.
If it is actually a file in use error, try ending your loops with pssehalt_2() to try to release any lock on the plb file.
Will pssehalt_2 l() stop my entire simulation?
In Progress txt ( i am exporting progress in txt) Error: Playback model (plb) not found. Model ignored Where as in main PSSE progess file in use message is popping.
I am running 100 simulations , File in use message is pooping only for thouse simulation where i have playback model referred in dyr file.
8 diagonal and 7 off-diagonal elements Model PLBVFU1 Bus 2204 [220KV POI 220.00] Machine "1 " : Error: Playback model input (plb) file not found; Model Ignored.
** LINES PER PAGE for FILE OUTPUT set to 9999999 File in use. F:\Anil\4(a).Dynamic_fault\Dyr_files\EQV_Model_R1_VRT1.dyr (OpnApplFil/OPNSEA)
The playback file must be in the working folder.
sav file in folder A where as dyr file is in folder B along with plb file
Make sure the plb file is in PSSE´s working folder!
Can you please explain PSSE´s working folder! I construction path of sav & dyr seperately and use them as required. As plb file is in the same folder of dyr i assume it takes it automatically
I even kept sav , dyr and plb in same folder still the error persist
Are you running PSSE from the GUI or from pyrhon?

Hi, were you able to fix it ? Am also having same issue, my .txt file says " Model PLBVFU1 Bus 260 [JENNER 4 240.00] Machine "1 " : Error: Playback model input (plb) file not found; Model Ignored."
