摘　　要：在总结国内外电力系统电压稳定性研究成果的基础上,将目前所采用的电力系统电压稳定性分析方法归纳为静态分析法和动态分析法,从理论依据、发展过程和应用成果等方面对这两类分析方法的研究现状加以分析和评述,得出结论:静态分析法不能很好地揭示电压稳定问题的物理本质和失稳机理,而要从动态因素上分析电压稳定的问题必须采用动态分析法,深入研究电压崩溃机理以及检验静态分析的结果;同时,建立适合于电压稳定性研究的系统元件动态模型和负荷模型是电压稳定问题研究的难点和关键。Based on summarizing research achievements about power system voltage stability at home and abroad,the current analysis methods for voltage stability in power system are classified as static analysis and dynamical analysis,and the fundamental theory,development of theoretical study and application situation of these methods are reviewed.It is concluded that static analysis fails to well reveal the physical essence and instability mechanism of voltage stability problem,while dynamical analysis can investigate voltage stability problem from dynamic factors,enable profound research on voltage collapse mechanism and verify the outcome of static analysis.Meanwhile,building dynamic and load models of system components fit for voltage stability research is the difficulty and key to the study on voltage stability.
