基于正则表达式的变电站集中监控信息解析方法

摘要

Along with the in-depth development of "large-scale movements in operation" system construction,the identifying of massive,complex and irregular centralized monitoring information has become the main problem in upgrading intelligent warning technology.By referring to the established characteristics of centralized monitoring information,the article puts forward a kind of centralized monitoring information analytic method based on regular expressions.The substation centralized monitoring information real-time analysis and automatic calibration are realized by extracting and analyzing the key elements of information with regular expressions,and identifying and matching the information in a maximum matching algorithm as a solid foundation for improving the intelligent warning technology.Finally,based on a practical application,the validity and practicality of the proposed method for the intelligent warning technology of centralized monitoring information are verified.%随着国家电网公司“大运行”体系建设的深入开展,海量、繁杂且存在不规则现象的集中监控信息的识别,已成为设备监控信息智能告警技术提升面临的主要问题.文中结合集中监控信息既定规则的特点,提出一种基于正则表达式描述的集中监控信息解析方法.通过正则表达式规则提取信息关键要素进行信息解析,并采用最大分词匹配算法进行信息识别匹配,实现变电站集中监控信息实时解析及自动校验,为设备监控信息智能告警技术的进一步提升奠定了良好基础.实际工程应用验证了所提方法有效性和实用性.
