Dynamic simulation of 2383bus polish system

edit

I found a couple of issues:

• generator at bus 10 was missed in the dyr (so no dynamics model was assigned to this online generator)
• MBASE of generator at bus 1024 was 0 (causing NANs) - I set this to 0.1MVA (=PGEN)

Following these changes, I was able to run a dynamic simulation and plot channel data.

The initialization check is not OK in my computer.

You cannot use GENCLS as this is the basic model of a generator (Classical Model) which is mostly used in texts in Power System Analysis. To capture the dynamics of your case, you may need to model your generators according to existing modeling guidelines (such as those published by IEEE). I suspect that NAN values were due to machine parameters. As mentioned, you need to accurately model the generators and associated control systems (e.g. exciter, governor, PSS, etc.)
