摘　　要：本文应用状态空间分析法对多机电力系统电压动态稳定性进行了详细探讨。内容包括建模;电压动态不稳定的特点以及与功角动态稳定性的区别和联系;发电机励磁控制包括稳定器(PSS)对于不同类型负荷电压动态稳定性的影响和作用;有载调压器和电动机典型负荷的电压失稳过程及电压动态稳定性的负荷模型问题等。In this paper detailed studies on the topics of the dynamic voltage stability of a mul-timachine power system are conducted via the state space method. It includes modelling, characteristic investigations of dynamic voltage instability, the relationship between the dynamic voltage stability and the dynamic rotor stability, the influences of the excitaton controls including a power system stabilizer (PSS) of a generator on the voltage stability with respect to different kinds of loads- The dynamic processes of the voltage instability of an on-load tap changer transformer and an induction motor as well as modelling problems about which are also discussed- A 5-node system is explored as an example for illustration-
