变电站继电保护故障信息远程传输系统设计

Design of remote transmission system for fault information of substation relay protection

为进一步提高电网故障处理效率与电力系统自动化运行水平,文中对变电站继电保护的故障信息远程传输系统展开研究。针对继电保护数据处理的功能需求,将系统分为故障监控、统计分析、运维管理和系统管理4个模块;针对系统的技术实现将其分为视图管理层、系统控制层和数据管理层3层体系结构。视图管理层以JSP和Struts标签为基础,采用了HTML和jQuery相结合的技术进行用户界面构建。系统控制层利用Struts框架中的Action对象完成功能配置,实现数据的显示、传输、调用、分析。数据管理层采用SQL Server数据库,通过采集变电站继电保护信息数据,利用Dao操作类,实现对数据信息的增减、查询功能。文中研究的内容对于实现电网的自动化运维管理,具有重要意义。

In order to further improve the efficiency of power grid fault handling and the automation level of power system,this paper studies the remote transmission system of relay protection fault information in substation.Aiming at the functional requirements of relay protection data processing,the system is divided into four modules:fault monitoring,statistical analysis,operation and maintenance management and system management.According to the technical realization of the system,it is divided into three layers:view management layer,system control layer and data management layer.View management layer is based on JSP and Struts tags,and uses HTML and jQuery technology to construct user interface.The system control layer uses the Action object in Struts framework to complete the function configuration,and realizes the display,transmission,invocation and analysis of data.The data management layer uses SQL Server database to collect the data of relay protection information of substation,and uses Dao operation class to realize the function of increasing,decreasing and querying data information.The content of this paper is of great significance for the realization of automated operation and maintenance management of power grid.
