Kundur under-damped modes

[xiaojiangsi]

the document says:

The Kundur's two-area system has under-damped modes and two coherent groups of generators. It is
suitable for oscillation study and transient stability studies.

how to do that? how to set the under-damped mode?

Underdamped modes can be found by performing an eigenvalue analysis. You can do andes run ... -r eig and inspect the output _eig.txt file for the oscillation modes.

This does not seem to be an issue so closing for now. Feel free to reopen it, or use "Discussions" if you have questions.
