摘要：

The dynamic system being studied is first divided into subsystems with each subsystem representing some physical part of the total system. The eigenvalues and eigenvectors of the subsystems are computed using standard library routines. The change in the eigenvalues between the subsystems and the total system caused by the interconnection between the subsystems is found using a method based on invariant subspaces. The greatest change occurs in the global eigenvalues, those which influence the response of more than one of the subsystems. These eigenvalues are of particular interest as they are the type that could cause interarea oscillations.
