| 摘 要： | 电力系统电压稳定性问题本质上属于动态问题，因此分析电压稳定问题必须考虑系统中主要动态元件的特征，文章以简单系统为例通过分析与计算研究了负荷，发电机及其调节系统等动态元件特性对小干扰电压稳定极限的重要影响，说明了基于常规潮流雅可比矩阵奇异性和Ｐ－Ｖ曲线拐点等电压稳定静态分析方法的不严格性。

| Abstract: | As power system voltage stability is ultimately a dynamic problem, the characteristics of main dynamic components must be considered in the analysis of voltage stability. The effects of dynamic components closely related to voltage stability such as load, generator and its regulating system on voltage stability limit are presented in this paper. The simulation results on a simple system show that the static voltage stability analytical methods based on the singularity of conventional load flow Jacobian matrix or the nose point of P V curve are not rigorous. |
