摘　　要：电压失稳表现为母线电压不可逆转的急剧下降,其灾难性后果是系统崩溃。描述了电压不稳定现象并进行了解释,分析和评述了各种基于静态和动态的电压稳定性研究方法,以及电压稳定的指标计算、预想事故选择和控制措施,总结了各阶段的研究成果。综述了尚未解决的问题,指出了电力系统中电压稳定性分析模型、分析方法和控制措施等方面的研究方向。Voltage instability manifests itself in a dramatic drop of transmission system voltages,which may lead to system disruption. The voltage instability phenomena is described and explained. Approa-ches to voltage stability study based on static and dynamic means are analyzed and reviewed,as well as the index calculation,forecasting accident selection and control measures. The achievements of all study stages are concluded. Considering the problems not solved,the research direction for analysis model,analysis method and control measures are pointed out. This project is supported by National Natural Science Foundation of China(59937150).
