摘　　要：基于对振荡中心(oscillationcenter)的位置及其漂移特征的研究,指出了振荡中心漂移的原因,并提出了失步中心(centerofout-of-step)的概念。认为失步断面联络线就是失步中心所在的联络线,并叙述了在不同振荡周期中,失步中心位置可能不同的原因。失步中心落到机组内部会对机组造成严重的破坏,影响系统的整体运行。基于振荡中心漂移的研究,给出了判断失步中心能否落到机组内部的判据。最后通过仿真进行了必要的验证。Based on investigation of the characteristics of the location and the movement of oscillation center, the reason for the movement of oscillation center is given. The definition of center of out-of-step,which lies in the tie-lines of out-of-step interface,is proposed. The paper also discusses the reason why the location of the center of out-of-step in different periods is likely to be different. If center of out-of-step lies in the interior of generator, the generator will be harmed severely and the whole system will be influenced. Based on the study of the movement of oscillation center, a criterion of determining whether the center of out-of-step will lies in the interior of the generator is proposed.Simulation is given as a necessary explanation.
