云峰电厂计算机监控系统一例系统性故障解析

Analysis of Systemic Fault on Computer Monitoring System of Yunfeng Hydropower Plant

简要地介绍了云峰发电厂计算机监控系统的构成与应用情况。针对2017年6月出现的一例典型系统性故障,根据现象进行了深入分析,解析出故障发生的深层次原因是系统内部操作员站经由网络的SQLServer数据库读写操作堆积影响到其余功能模块间的数据交互使之受阻,为同类自动化平台具有相似场景的工业应用的故障处理提供了参考。

It briefly introduces the composition and the application computer monitoring system in Yunfeng hydroelectric power plant.Aiming at a typical systemic failure in June 2017,it analyzes the phenomenon in depth.The root cause of the failure is analyzed that the operation stack of the operator station in the system via the SQL Server database of the network will affect the data interaction between other functional modules and make it blocked.It provides reference for industrial applications with similar scenarios on similar automation platforms.
