摘要

为提高输电线路因灾害引发故障跳闸的重合成功率

进一步保障电网供电的可靠性和连续性

基于历史的线路跳闸数据挖掘灾害类型、线路信息与重合闸成功率之间的关联规则。采用Apriori算法搜索频繁项集

并设置支持度、置信度和提升度3个参数提取有效的强关联规则

结果表明:雷击、鸟害引发线路故障跳闸的重合成功率较高

分别为93.01%和89.04%;风害、冰害引发的线路故障跳闸不易重合成功

重合不成功率分别为93.33%和84.72%;在不同电压等级的输电线路中

500 kV遭受雷击和冰害的影响最为严重

引起330 kV线路故障跳闸重合不成功的主要灾害为风害、外破。研究成果可为输电线路重合闸策略优化提供依据。

Abstract

In order to improve the reclosing success rate of transmission lines due to disasters

which can guarantee the reliability and continuity of power supply

historical fault data is taken to excavate the association rules among disaster types

line information and the reclosing success rate. Apriori algorithm is adopted to search the frequent item sets. Then the support

the confidence and the lift are set to extract the efficient and strong association rules.The results show that the reclosing success rate of transmission lines due to lightning and bird are higher

respectively 93.01% and 89.04%. And the fault tripping caused by wind and icing are not easy to succeed

whose rate are93.33% and 84.72% respectively. In the transmission lines of different voltage levels

effects of lightning and icing in 500 kV line are the most severe

and the main disasters which caused the failure of transmission line’s reclosing in 330 kV line are wind and external damage. The research results can provide guidance to optimize the strategy of transmission line’s reclosing.
