广州蓄能水电厂EventLog系统

EventLog System of Guangzhou Pumped Storage Power Plant

广州蓄能水电厂机组运行事件记录(EventLog)系统记录生产运行的重要信息,对设备故障的定位和排除起着不可缺少的作用,也是安排电厂设备运行和检修计划的重要依据。该系统使用Java2平台企业版(J2EE)技术作为系统的开发框架,通过Java的串口通信技术,从监控系统的串口收集信息,实现到数据库的海量存储,从而提供方便的数据在线和离线的查阅、辅助排障以及丰富的统计和分析等功能。文中介绍了EventLog系统组网结构、设计方案和采用的关键技术,分析了该系统的功能。多年实践证明,该系统在生产运行中发挥了重要的作用。

The EventLog System of Guangzhou Pumped Storage Power Plant records important operation information and plays an indispensable part in the positioning and removing of equipment malfunctions. It is also an important reference for the management of equipment operation and maintenance. The system, which is based on the framework of J2EE technology, collects information from the serial ports of the monitoring and control system with Java serial ports communication technology, and stores large volumes of data in the database to offer convenient functions including on-line and off-line data query, assistant malfunctions removing, statistics and analysis, etc. The network structure, the design scheme and the key techniques of the system are introduced, and its functions are analyzed. The operation practice shows the important role of the EventLog system in the power plant operation.
