为了进一步探索电力系统的电压稳定机制，对已有的电压稳定分析方法进行了比较和总结。电压稳定静态分析法研究的是系统动态方程的平衡点问题，只能给出电压稳定的必要条件，由于算法简单快速，得到广泛应用；电压稳定动态分析法研究的是深入理解电压稳定机理和进行电压稳定控制的重要基础和工具。介绍了以电压稳定数学模型为出发点，在统一的数学模型框架内，分析了电压稳定静态分析法（包括特征值分析法、模式分析法、灵敏度分析法、连续潮流法和崩溃点法）和动态分析法（时域仿真分析法、小扰动分析法和分岔分析法）的理论基础、数学模型、物理意义、适用范围等信息，以期为合理选取电力系统的电压稳定分析方法提供参考。

In order to further explore the mechanism of voltage stability of power system,compared and sum-marized of the existing analysis methods of voltage stability.Static voltage stability analysis is the study of the equilibrium problem of system dynamic equation,can only given the necessary condition of voltage stability. Because of its simple and fast algorithm,it is widely used.Dynamic voltage stability analysis is the study of the deep understanding of the mechanism of voltage stability and important basis and tools for voltage stability control.Introduces the mathematical model for voltage stability as a starting point,the unified mathematical model of the framework,and analyzes the static voltage stability analysis (including the eigenvalue analysis, model analysis,sensitivity analysis,the method of continuous tide and collapse point method)and the dynamic analysis method (the time domain simulation analysis,the small disturbance analysis and bifurcation analysis) of the theoretical basis,mathematical model,the physical significance,scope of application,which can help to provide the reference of reasonable selection of power system voltage stability analysis method.
