| 摘要: |
| 中国是世界上架空输电线路覆冰舞动最严重的国家之一。近年来输电线路舞动跳闸呈现出频率高、影响范围大的特点。提出了一种基于灰色关联模型的输电线路舞动预警方法，根据舞动故障发生的主要原因，建立指标体系，并根据各指标的影响程度采用层次分析法对各个指标分别赋以权重。据此再利用灰色关联理论将当前数据与参考数据进行关联度分析，从而计算当前线路发生舞动故障的危险指数，对故障发生的可能性进行预测。检修人员可以基于预测结果选择相应的巡检策略，从而做到有针对性地预防舞动故障，提高巡检效率，进一步减小输电线路舞动带来的危害。 |

| Abstract: |
| China is one of the countries which have serious ice-coating galloping of overhead transmission lines in the world. In recent years, the galloping trip of transmission lines presents the characteristics of high frequency and wide influence. An early warning method of transmission line galloping based on grey relational model is proposed, which establishes the index system according to the main causes of galloping fault and then assigns weight to each index according to its influence degree. Based on this, the grey relational theory is adopted to analyze the relational degree between the current data and the reference data, then the occurring risk index of galloping fault in the current line is calculated and used to predict the possibility of the galloping fault. Based on the predicting results, maintainers are able to choose the corresponding inspection strategy targetedly to prevent the galloping fault, so the inspection efficiency is improved and the harm of the transmission line galloping is reduced. |
