电网故障发生后，巡维中心主站可以从电网运行控制中心的各主站系统收集到关于故障事件的大量告警和状态信息，这往往给运行人员造成很大的工作压力，也难以保证对事故告警判断和处理的正确性。提出的巡维中心驾驶舱（运行管理系统）的告警信息处理和故障设备定位功能将各主站信息收集至巡维中心一体化信息平台实时库后，采用大数据存储和数据挖掘技术，对故障的特征以及与设备的关联关系实现提取，结合周边变电站信息，对告警变电站的运行状态进行在线实时分析和推理，采用决策树技术定位发生故障或出现危险情况的具体设备和故障原因，协助运行人员及时地分析和处理事故。

When a network failure occurs,the master sta-tion in the O & M center will gather too many alarms and too much state information from each station system of the operation control center of the grid,which often exert too much pressure on the operating staff and make it difficult to ensure correctness of the judgment and treatment of the alarms. The O&M center dashboard (operation management system) proposed in this study,equipped with the alarm information disposal and fault device location functions,can send the information collected from every station to the real-time database of the information integration platform in the O & M center where the mass data storage and mining technology is used to realize extraction of the fault feature and association with equipment. Finally,the operating state of the alarm substation is analyzed and deduced in the real-time online based on the operating conditions of the peripheral stations and the specific failure or dangerous device and fault reasons are located by decision tree to help the operating staff to handle accidents in time.
