Abstract
According to the character of the equilibrium point of the complementary-cluster center-of-inertia mapping system, the trajectories of the two complementary clusters of generators can be classified into five kinds of modes, namely stable-node, unstable-node, stable-focus, unstable-focus and saddle. Therefore, microscopic structures of the trajectories can be analyzed. Taking resynchronization after a series of slips as an example, the mechanism of multi-machine dynamical changes with imperceptible variety of parameter is analyzed. No matter how little a parameter changes, if and only if the starting point of a saddle-mode section on the phase plane changes from one side of the stable manifolds to the other side, the dynamics afterwards is entirely different.
