摘　　要：由于负荷的快速增长以及市场机制下电力系统运行方式的频繁调整使得电网可能接近稳定极限运行,这使得电网的电压稳定问题变得越来越严重。如何在事故扰动情况下快速而准确地评估电网的电压稳定性具有重要的意义。阐述了事故筛选和排序的基本概念和评估的指标类型,对现有的各种事故筛选和排序方法进行了总结与述评,并指出了此领域研究存在的问题。The rapid load growth and frequent adjustments of the power system operation mode under the market mechanism make power grids operate near its stability limit, which makes the grid voltage stability problems become more serious. Under some disturbance circumstances ,how to quickly and accurately assess the grid voltage stability is of great significance. In this paper, basic conceptions and types of evaluated indexes about contingency screening and ranking is first interpreted, and the kinds of the methods of the existing contingency screening and ranking are summed and commenterized .Also, it is proposed that the research of contingency screening and ranking will exist problems.
