摘要：

对电压暂降的多源属性进行分析，不仅能为供电工程的规划设计、设备选型、运行维护等环节提供全过程技术支撑，还可以有效评估电能质量事件的风险及其严重程度。该文提出电压暂降的多源属性贡献度排序方法。首先，列举电压暂降的多源属性，将其分为内源属性和外源属性；然后，采用设备兼容度指标，计算多源属性下设备的暂降兼容度，并建立基于层次分析法的三层致因体系，针对多源致因属性的权重进行计算；最后，利用蒙特卡洛法进行仿真，结合实际工程数据，分析多源致因属性下发生电压暂降的严重性程度，评估结果验证该方法可行。

Abstract: The multi-source attribute analysis of voltage sag can not only provide whole-process technical support for power supply engineering design, equipment selection, operation and maintenance, but also effectively assess the risk and severity of power quality events. In this paper, the contribution ranking method of voltage sag is proposed. Firstly, the multi-source attributes of voltage sag are listed, which can be divided into internal attributes and external attributes. Then, the equipment compatibility index was used to calculate the sag compatibility of the equipment under multi-source attributes, and a three-layer causation system based on the analytic hierarchy process was established to calculate the weight of multi-source causation attributes. Finally, monte carlo simulation was used to analyze the severity of voltage sag under multi-source causation attributes, and the feasibility of the method was verified by the evaluation results.
Keywords: voltage sags;multisource attribute;analytic process hierarchy;equipment compatibility index
