摘要(Abstract)：

故障筛选与排序是电力系统稳定评估的重要部分。提出了一种用于含直流馈入的受端电网故障筛选与排序方法。首先,构建了考虑电网暂态电压稳定性、静态电压稳定性、功角稳定性、潮流转移特性和网架支撑能力的故障严重程度综合评价指标,克服了单一指标评价的局限性。然后,采用层次分析法和熵权法相结合的方法确定各指标的权重,可兼顾电网运行方式人员的经验和指标数据的客观信息。在此基础上,应用逼近理想解法对故障严重程度进行排序。最后,以含特高压直流馈入的湖南电网为算例进行分析,结果验证了所提故障筛选与排序方法的有效性和实用性。

关键词(KeyWords)： 故障筛选与排序;直流输电;受端电网;湖南电网;主客观权重;逼近理想解法
