摘　　要：严格证明了静态和小扰动电压稳定极限只决定于系统组成元件的稳态特性，与系统的暂态过程无关。在考虑实际动态过程中各种元件稳态特性的变化相应修正常规潮流雅可比矩阵后，求得的静态电压稳定极限和小扰动动态分析得到的电压稳定极限完全相同；从而说明可以利用计算量小的静态电压稳定分析方法研究大规模电力系统的电压稳定性。最后以ＳＶＣ 为例说明了建立考虑系统动态元件特性的静态电压稳定分析模型的方法。This paper gives a strict proof that the small disturbance voltage stability limit depends only on the steady state characteristics of the dynamic components of the system and is independent of their transient characteristics. The static voltage stability limit acquired after considering changes of the steady state characteristics in dynamical course is consistent with the small disturbance voltage stability limit. These show that we can use static methods with less calculation in voltage stability analysis for large scale power systems. Finally, this paper constructs SVC's new model as an example, to illustrate the method of constructing the new static model of voltage stability analysis taking account of dynamic components of the system.
