Remote operation monitoring and analysis of intelligent substation regulation

文章针对智能变电站调控远方操作监视及分析,运用操作对象特征识别和控制流程分步关联的调控远方操作多协议关联建模和分析技术,解决了调控远方操作全过程监视;构建智能变电站调控远方操作交互模型和故障诊断知识库,建立了调控远方操作故障诊断有向图,通过收集远方操作事件驱动故障诊断有向图通路搜索,解决了调控远方操作故障的分析诊断。基于上述技术研发的智能变电站调控远方操作监视系统已在福建泉州电网投入应用,实现了智能变电站调控远方操作全过程监视,辅助运行维护人员对智能变电站调控远方操作异常进行分析诊断,通过准确定位故障环节,有效缩短了故障处理时间,同时发现自动化系统和设备缺陷,指导自动化厂家对产品进行有针对性的消缺改进。

Aiming at the monitoring and analysis of dispatching remote opertion in intelligent substation,this paper applies the multi-protocol correlation modeling and analysis technology based on feature recognition of operation object and step-by-step association of control flow to solve the whole process monitoring of remote operation in intelligent substation.By constructing the interaction model of remote operation in intelligent substation and the database for fault diagnosis of remote operation,the directed graph used in fault diagnosis of remote operation is established.The remote operation events are collected to drive searching for conduction path of the directed graph used in fault diagnosis of remote operation.Through searching conduction path of the directed graph,the cause of remote operation fault is found final.Based on the technology,the monitoring and analysis system of remote operation in intelligent substation has been developed and put into application in quanzhou power grid of fujian province,realizing the whole process monitoring of remote operation in intelligent substation,assisting operation and maintenance personnel to analyse and diagnose abnormality of remote operation in Intelligent Substation,effectively shortening fault processing time by accurately locating the fault links,at the same time,helping manufacturers to find the defects of automation system and equipment and improve their products.
