【摘要】 电力系统稳定问题是理论和概念很强的问题．其中功角稳定的研究已经很成熟．以单机无穷大系统来阐述这一问题也很清晰、透彻地讲请其物理意义．电压稳定是近来大家突出关心的问题，能否以简单的模型揭示它的基本概念和行为，使初学者便于理解和接受是相当必要的．本文就简单网络的建立和应用几种常用的电压稳定分析方法进行分析，引导出电压稳定问题的一些基本概念和特性．更多还原

【Abstract】 The voltage stability problem has benn paid much attention to for all of us. This paper intents to establish a simple network model for describing the basic concepts and behaviours of the Static voltage stability,just as a single unit to aninfinite bus model for the problem of the angular Stability. AppliCation of several analytic methods shows the model is successful.更多还原
