摘要
针对人工识别匹配雷击故障和跳闸线路的弊端,提出一种基于正则表达式的输电线路名称的匹配方法,协同利用雷电定位系统、调度管理系统数据库的节点资源,匹配跳闸线路和线路台账的映射关系。该方法以雷击事故后辅助查找跳闸位置和判断跳闸原因为应用场景,以雷电定位系统为运算平台。匹配过程分为数据库中关键字段预处理阶段和模糊匹配阶段,其预处理阶段提取过滤线路名称条目中的伪代码,匹配阶段根据预处理的规范化结果匹配线路名称。实际应用匹配识别率达到100%,可及时得到线路跳闸与雷电活动相关性分析结果,良好适用于线路跳闸数据库中的信息。
Aiming at the disadvantages of manual identification matching lightning strike fault and tripping transmission line, this paper presents a method for matching transmission line names based on regular expressions, joint use of lightning location system, scheduling management system node resources, matching relationship between matching trip line and line account. The application scenario of this method is to assist in finding trip lines and the lightning location system is used as the computing platform. The matching process consists of key field preprocessing and fuzzy matching, the preprocessing phase is the pseudo code extraction in the filter line name, the matching phase is matching the line name according to normalization results of preprocessing. The application result show that the identification rate is 100%, the correlation analysis results of line trip and lightning strike are obtained, which is well suited for line trip database information.
