Application of catastrophe theory in power system

This paper study on the chaotic oscillation, accident chain function and mutation theory of interconnected electric power system and draw a conclusion that: power system has small water chestnut chaos and has the probability of evolution from local chaos to the whole; power system has the accident chain characteristic, which is the triggering events of system interconnecting culprit; oscillation differential equation and accident chain function has the characteristic of mutation, for which, the system will still be disturbed from equilibrium condition to an un-regressive catastrophe state in a certain transition point, although it can regress to the stable state from a small sub region depart from the equilibrium position
