电力系统中各元件动态对电压稳定性的影响分析

Analysis of the Element Characteristic Influence on Voltage Stability

本文采用小干扰分析方法详细分析了电力系统中各元件动态对静态电压稳定性的影响,并给出了简单的物理解释,对静态电压稳定研究中所应采用的系统模型提出了自己的看法。采用的小干扰分析程序对目前普遍认为与电压崩溃现象密切相关的系统动态进行了详细的模拟。

In this paper the perturbation method is used to analysis the influence of the main element charactcristic on voltage stability, and some ideas presented to select system model in studying steady-state voltage stability.In the used algorithm, the dynamics of load. OLTC and generator are considered in detail.
