摘要
在一定的条件下，系统的动态行为对于参数的变化非常敏感，在２机系统上也会表现出极其丰富的混沌现象。文中给出了２机系统失步后在没有外加控制的条件下再同步的实例，以及相关的混沌现象。用ＥＥＡＣ理论解释了该现象的机理，以定量方法揭示了貌似无序的现象中的有序性，并在多机系统上得到验证。
Despite that resynchronization has been studied for forty years,chaotic characteristic of this phenomenon has not been discovered.In this paper,resynchronization of unstable power systems without governor actions is investigated on a 2-machine multi-node system,and it is illustrated how sensitive the dynamics are to the system parameters.The mechanisms are revealed by using Extended Equal-Area Criterion(EEAC).The necessary and sufficient condition of the phenomenon is also derived as that the kinetic energy equals to zero when the system passes through the dynamic saddle point.This conclusion is also confirmed on a multi-machine system.
