About one week ago ,I asked a question about how can i use PSS/E to calculate critical clear time through Python.But i still can not slove this problem with my software PSS/E which version is 33. So,i still want to need someone to help me to give me some useful ideas about this question or find another arguments to replace the use of critical clear time(CCT). I almost have no idea to solove this problem and urgently to build my dataset about CCT

Check the post "MPjobs tool for PSSe runs in Parallel". It has a link to download my tool, MPjobs and it includes a critical clearing time (CCT) study example. Follow the instruction in the readme.txt file.
The CCT data input is in cct_1d.ini and the code that runs the study is in scripts\cct_1d.py. In this example, MPjobs runs multiple instances of cct_1d.py according to data defined in cct_1d.ini. The corresponding *.out and *.log created will have to be analyzed to assert CCT outcome.

The cct_1d.py expects to find a converted case and a snap file in the path specified in the ini file. When you have a non-converted case and a dyr file, the converted case and snap file can be created with the following script:

psspy.case('my.sav')
psspy.conl(0,1,1,[0,0],[ 100.0,0.0,0.0, 100.0])
psspy.conl(0,1,2,[0,0],[ 100.0,0.0,0.0, 100.0])
psspy.conl(0,1,3,[0,0],[ 100.0,0.0,0.0, 100.0])
psspy.cong()
psspy.ordr(0)
psspy.fact()
psspy.tysl(0)
psspy.tysl(0)
psspy.save('my_cnv.sav')

#** Read DYRE records -  system dynamics + solar PV dynamics
psspy.dyre_new([1,1,1,1],'my.dyr','','','')
#** Save snapshot for dynamics
psspy.snap([-1,-1,-1,-1,-1],'my.snp')

If specific channels are monitored, plots of those channels for the multiple *.out files can be done to visualize the CCT outcome (for plotting check the post "Channels - tool to process outs files").

sorry,i can't find any file about cct in your link . Did you delete them ?

The link to download MPjobs is in the third paragraph of that post. CCT is an example included in the install.

Yes,i download MPjobs in your post.But i really can't find any example about CCT in MPjobs_jconto_20230911

Sorry for the missing files. Please download the updated zip file MPjobs_jconto_20240102 and follows the instructions given above.

Sorry for interrupting you again.I have successfully run the base simulation that you provided.but i want to run the case of IEEE 39 power system.I have the file of IEEE 39.sav and IEEE 39.dyr.So,next,what can i do to achieve my goal of doing the simulation of IEEE39's CCT calculation
