Hi, I want to use PSS/E to calculate critical clear time(CCT) through python.But i can't find the corresponding API code to solove this problem . So i want to ask for help to slove this . If someone can tackle this problem ,i will show my thanks for you
Use a for loop and perform dynamic simulations with increasing fault clearing time until instability occurs.
EDIT:
Critical Clearing Time (CrCT) calculation was introduced in PSSE rev 35.5.
thank you for your comment . i will try it
I have further question about CrCT calculation. I always got the error message "Generators are not "converted"" and the simulation stopped. It seems like I do something wrong when saving the snp file. How to get a converted case when I load the .sav and .snp file? Thank you.
hello，when i do this ,i have one more question . which API or arguments can i use to determine the system's state like stable or unstable . Maybe i can use TSI or frequency?
Generators and loads must be converted before initialising. See Figure 14.4 in PAG, vol 2.
Instability is checked with "Angle spread" channel. Add channel with Select Channels by Subsystem - Machine angle statistics.
