电网调度控制系统数据库间同步故障分析及处理

Analysis and Treatment of a Synchronization Fault Between Databases of Power Grid Dispatching Control System

针对一起电网调度控制系统安全I、III区数据库同步故障,从历史服务器运行状态、同步进程状态、同步日志等方面进行排查分析,最终发现该故障由关系型数据库非必要同步数据表异常更新造成。同时结合该起故障,提出了此类故障的若干防范措施,可为同行预防和处理此类故障提供参考。

A database synchronization fault in zone I and zone III of the power grid dispatching control system is analyzed from the aspects of historic server running status,synchronization process status,and synchronization logs.It is found that the fault is caused by the abnormal update of unnecessary synchronization data tables of relational databases.At the same time,some preventive measures are put forward,which can provide reference for the peers to prevent and deal with this kind of fault.
