Hello Python/PSSE gurus!

How do I validate N-1-1 contingencies in PSSE? For example, if I have a violation and I want ascertain that the 2nd contingency actually have impact on the violation then what would help me filter out those 2nd contingencies due to irrelevance. I have hundreds if not thousands of N-1-1 results in the acc files so it's not possible to validate one by one manually to see the impact (*thanks to member perolofi *). Allow me to elaborate on the question, I am asking if there's a way to apply any logic/code that can help me get rid of the irrelevant contingencies because I'm not 100% sure if PSSE's has shift factor calculation or something similar by which I can get rid of the thermal violations. Thanks in advance!

Use a script for the validation. Perform N-1 for each N-1-1 contingency and compare the violation.

Thanks! Is it possible to see a sample code? So, what you are saying is to compare the results from N-1 with N-1-1 for the same monitored elements and exclude if they are not within a certain percentage of the first N-1, right?

Yes, but exclude N-1-1 if they are WITHIN a certain percentage of N-1.

Compare with the impact of an N-1 contingency.
