摘要
提出了一种基于网络结构保持模型，通过对暂态过程中运行变量的分析来评价电力系统暂态稳定性的分析方法，定义了运行变量的临界割集及其稳定指标，给出一种快速求取临界割集暂稳极限传输功率的迭代算法。算例说明了该方法的有效性。
Using the model which preserves network structure. this paper analyses operational variables during transient period, and presents a kind of analytic method to assess power system transient stability. Based on operational variables, the critical cutset and its stability index are defined. An algorithm is offered to calculate the transient stability power limit of the critical cutset. Examples illustrate the validity of the proposed method.
