| 摘 要： | 本文利用潮流方程的二阶非线性特点，从满足电压崩溃临界状态的边界条件出发，再由潮流方程的一对多根解（高电压解ｘ０和低电压解ｘ１）组成的新变量的一些性质，提出了一种快速，简便又满足精度要求的计算临界状态的模型和算法。

| Abstract: | This paper proposes mathematical formulation of the critical state of voltage collapse and its fast algorithm in electric power systems. The formulation is based on the boundary necessary condition of the cirtical state of voltage collapse and the application of second order nonlinearity in load flow equation. A new variable vector b is compose of high voltage solution xo and low voltage solution x1 in multiple load flow solutions, and some specific properties corresponding to new variable vector b are used to formulate the problem. |
