基于语义分析的D5000遥信信息生成与校核方法

A Method for Generating and Checking D5000 Alarm Information Based on Semantic Analysis

针对电网集中监控信息描述模糊、间隔不明和告警级别缺失等问题,提出一种采用语义分析技术的D5000遥信信息生成与校核方法。借鉴专家知识库理论,通过编程实现D5000遥信模版的自动生成功能,并通过字符分解自动提取遥信信息表中校核模型所需的基本逻辑变量,进一步对比分析ON2000遥信信息表与D5000规范模版中的变量,实现D5000遥信信息表的校核纠错功能。某地区电网110 kV变电站遥信校核实例验证了所提出方法可有效地简化人工校核流程,提高信息处理效率,从而起到优化监控信息管理的作用。

To solve the problems of vague description, undefined interval and missing alarming level existing in centralized power grid monitoring information, this paper proposes a method for generating and checking D5000 alarm information based on semantic analysis. Firstly, the automatic generation of D5000 alarm information table is realized by referring to expert knowledge base theory. Besides, the basic logic variables are automatically extracted from the alarming information table by character decomposition. Based on a comparative analysis of D5000 and ON2000 information tables, the checking and error-correcting function is also accomplished. A case study of a 110 kV substation shows that the method is valuable in simplifying the manual checking process, improving the information processing efficiency, and optimizing the management level of monitoring information.
