近几十年来，电力系统向大电网、高电压和远距离输电发展，虽然对提高经济效益、促进环境保护起到了重要作用，但是也给电力系统的安全运行带来了新的问题，电压失稳就是其中之一。
电力系统电压稳定性是电力工程界的研究热点之一。电力系统电压不稳定、电压崩溃事故是电力系统丧失稳定性的一个主要方面，因为其造成的经计损失巨大，影响面积大，社会影响严重，所以是电力系统安全运行的一个急需解决的问题。
本文首先阐述了研究电压稳定的重要意义、电压稳定的定义和分类。从静态和动态两个角度分析了电压失稳的机理，对电压稳定做了静态和动态的分析，并举出了常用的数学模型。而后又对电力系统元件的无功一电压特性及其对电压稳定性的影响做了分析。例举了美加8.14大停电事故，来启发我们如何对预防和保持电压稳定采取措施。对具体实例使用MATLAB中的仿真工具中的simulink进行动态时域仿真。
In the recent several dozens years, electrical power system to bigelectrical network, high voltage and long-distance range electrictransmission development, although to enhanced the economicefficiency, the promotion environmental protection vital role, butalso gave the electrical power system the safe operation to bring thenew question, the voltage has lost steadily is one of them. The electrical power system voltage stability is one of electric powerengineering research hot spots. The electrical power system voltageunstable, the voltage collapse accident is the electrical power systemloses a stable principal aspect, because it creates after counts theloss greatly, affects the area to be big, the society affectsseriously, therefore is an electrical power system safe operationurgent need solution question. This article first elaborated the research voltage regulation vitalsignificance, the voltage regulation definition and theclassification. Analyzed the voltage from the static state
