Revision history [back]

Hello,

This might be a rather amateurish question as I'm just a beginner in using PSS/E. I'm required to run some dynamic simulation cases in PSS/E v33.12, which seems to work fine with a combination of .sav, .dyr and .dll files, i.e. i do not get any errors and can apply the fault at a particular bus and generate all the output plots.

However in addition, I had also received (from an external source), a folder comprising a bunch of *.mac files, which seem to correspond to AVR, Governor, exciter models. Now these *.mac files seem to be included inside the .dyr file, as user defined models (‘USRMBL’), but not getting initialized when the .dyr file is opened or loaded. After opening the .sav file, when i proceed to open the .dyr file in PSS/E, then I'm receiving the following messages in the Output Bar/Progress window for each of the *.mac file:

Messages for process modelfiles Data-driven user models not initialized (004523) *.mac (mdflInputs)

So my question is, is there a way to initialize these *.mac files prior to running the dynamic simulation cases ? Like i am able to load all the *.dll files pretty easily through Tool/Load Model Library.. Is there a similar way that all the *.mac files can also be loaded and initialized?

Would appreciate some kind feedback! Thanks in advance!
