It would be hard to find which branches in the MATPOWER data constitute a
three-winding transformer if you don’t have the original cases. I guess you’ll
just have to choose sets of three branches and assume they constitute
three-winding transformers.

Subject: About three winding transformers and contingency analysis
Dear all
I want to run a contingency analysis (n-1) using Matpower 5.1
The code I have is automated to take out one branch at a time.
However, three winding transformers are modelled as three different branches.
So, If I want to simulate the outage of such a transformer I must take three
braches at a time.
The problem consists on identifying the three winding transformers.
How do I identify a three winding transformers within the mpc.branch matrix?
I tried to do it by checking different baseKV in mpc.bus; however all baseKV
values are the same.
Has anyone had the same inquiry?
Can anyone give me some hints?
Best regards,
Jesús López
