Follows my question from https://psspy.org/psse-help-forum/question/1500/cant-find-exdc1-model-in-psse-33/?answer=1502#post-id-1502, I converted dyd to dyr (dyr codes are shown as below). I ran on both PSS/E 32 and 33, encountered problems as point 1 and 2.

1.With PSS/E33, I am able to initialize it, but could not run it.

2.With PSS/E32 when I initialize it, it crashed.

Found the error, "/" in 34 'GENROU' should be placed at the end. Now it runs

It seems you are missing an exciter model for machine 39.

I am attaching a zip file [once dowloaded, replace gif with zip and unzip it] with my version of a dynamic data set for the ieee39 case, with governors and pss models (not included in the original) and made changes to the Genrou model to match zsorce values in the case. The ieee.err file is the progress window output as the 'no-disturbance' test is applied. Other data file are the conl.idv to convert the load, channels.idv to define the channels and adjustparam.idv to change run settings. C:\fakepath\NewEnglandIEEE39.gif

@jconto, thank you very much, it works great for me, and governors and pss models are bonus for me.

@jconto, do I have any chances to get negative and zero sequence impedence for this 39 bus? I might use it for SLG analysis. Thanks.

SC ( 2014-03-19 09:01:30 -0500 )edit

I do not have sequence data for this network. The savnw.sav case provided by pti (example folder inside the psse installation folder) does have sequence data.

@jconto, still good to know about this. Thanks again.

@jconto

Hi , I did download the attachment, and everything seems okay (no error or initial condition suspect). However, after any fault or any kind of contingency (I tried various cases), rotor angles deviate and not converge.

Would you please let me know what is probably wrong with my approach which cause this problem. Since, it seems that others don't have such problem.

Thanks a lot,

It could be that the case is at the edge of instability (high load, etc.) and any fault will take gens out of synchronism. It could be that the fault applied last too long. can you post a sample of the fault applied that causes the problem? (an idv file representing the fault)
