摘　　要：在学到理解电力系统电压稳定概念的前提下,牢固掌握电压稳定机理是研究电压稳定的基础环节。从失稳机理的角度来看,导致电力系统电压失稳的原因包括:负荷的动态恢复特性,电力系统受端电压支撑不足,电力系统送端的供电限制,以及综合负荷因素。从以上四种角度定义的电压稳定机理进行了综合分析和评价,并归纳总结了各类定义方式的特点及优缺点。On a clear understanding of power system＇ s vohage stability conception, this paper points out that to master the mechanism of voltage stability is the key link of controlling the voltage stability. From the point of view of instability mechanism, there are some factors which can lead the instability of power system＇ s voltage. These factors include the load＇ s dynamic recovery features, the insufficient support of voltage in receiving end of the power system, the supply constraints from the sending end of power system, as well as the comprehensive load factors. This paper carries on comprehensive analysis and evaluation of all above voltage stability mechanism＇ s definitions which defined form four different perspectives.
