About the kinetic energy of mutual motion of synchronous machine rotors under disturbance in a large power system [PDF]
E3S Web of Conferences, 2021 The article shows the analysis of the components of the mutual motion of the synchronous machines rotors in the transient process under disturbance conditions. It is shown that the representation of the original EPS can be represented by a two-machine equivalent, relative to the section in which stability is violated.

Kink-antikink asymmetry and impurity interactions in topological mechanical chains [PDF]
, 2016 We study the dynamical response of a diatomic periodic chain of rotors coupled by springs, whose unit cell breaks spatial inversion symmetry. In the continuum description, we derive a nonlinear field theory which admits topological kinks and antikinks as
