Hello, I'm attempting to run Python scripts for PSSE. I was wondering if it is possible to access the variable 'SBASE' in Python?

Thanks!

Hello Everyone,

I am currently working on a user defined model and had a question pertaining angle and frequency calculation. At the moment I have gotten acceptable responses during a three phase fault in which the power and voltage goes down. What I don't understand is that my frequency goes down when it should go up. The system is composed of an infinite bus, a POI bus and my generator representation with the user defined model. I look at other generator representations in place of mine and see that the frequency goes up immediately during the fault. MY model has the frequency go down. Similarly, the angle is the reciprocal of mine during the fault (it is swinging the exact same, but opposite). My current injection seems sound, but the frequency/angle response is not. I have matched the waveforms between my model and others pre fault and they match. It seems like a simple sign error, however this does not seem to be the case as any changes distorts either the initial condition or fault response behavior. I'm wondering how the bus angle starts progressing opposite of other models. Any help would be great. Thanks!

Hello,

I am attempting to build user defined models in PSSE with Fortran. Unfortunately when I look through some examples, they all have functions that I cannot find documentation on. Are there any sources on the functions available within PSSE?

I have also tried to create a .dll file from the provided .obj files in the IPLUSR folder (v33) and was unable to create one.

Hi everyone,

I'm attempting to create a user defined model and the associated .dll file. Unfortunately whenever I attempt to compile my FORTRAN files no .dll is produced. I was curious if anyone had any basic files used to produce a .dll that they'd be willing to share?

Thanks!

Hi all,

I'm attempting to build a User Defined Model and I cannot find where to build the .dll file. I thought you would use the Environment Manager (PSSE EnvMgr-6.0.0.win32py27py25) in my case, however that doesn't have any options when I open it besides modify, repair, and remove. All references I have seen point to opening the Environment Manager like it's its own program and using your model files in FORTRAN in it, however I don't see this as the case.

Thanks!
