摘要
通过对智能变电站设备在故障时的告警信息的分类处理和推理,实现对故障的智能告警。文章梳理智能告警的工作流程,根据智能变电站告警信息的严重等级对信息进行分级处理并进行报警信息展示,通过对智能变电站SCD配置文件的解析,绘制变电站二次的网络拓扑图并与告警信息相互关联,缩小故障点的定位范围。通过智能告警专家系统建立推理知识库,在告警时快速定位故障并消除,实际的推理案例验证了方法的有效性。
Through the classification and reasoning of alarm information of smart substation equipment in case of fault,the intelligent alarm of fault is realized.In this paper,the work flow of intelligent alarm is sorted out according to the severity level of alarm information in smart substation,the information is processed and displayed in different levels.Through the analysis of SCD configuration file in smart substation,the secondary-circuit network topology map of substation is drawn and correlated with alarm information,so as to narrow the location range of fault points.Through the intelligent alarm expert system,the inference knowledge base is established to locate and eliminate the fault quickly.The validity of the method is verified by a practical reasoning case.
