摘　　要：厂级监控信息系统(SIS)是电厂信息系统的发展方向,它在保障安全生产、降低成本、实现信息共享和管控一体化等方面发挥了重要作用。介绍SIS在湖南耒阳电厂的实际应用,重点介绍SIS的网络结构、数据库平台、应用模块的现场应用情况。耒阳电厂SIS主要功能包括实时监视和查询、厂级经济指标计算、设备状态监测、性能分析、厂级负荷优化分配、机组运行操作指导等,采用了GEFanuc公司的实时历史数据库iHistorian和监控组态软件iFIX作为SIS的基本软件平台,并从网络和软件上实现了系统的冗余功能,保证了系统的稳定可靠运行。SIS, as the development of information system in power plant, plays an important role in safer production, lower cost, information sharing and integration of management and control. The practical application of SIS was introduced in this paper, especially that of the network structure, database platform and application module. SIS in Leiyang Power Plant is of the following main functions such as real-time monitoring and searching, computation of plant-level economic indicators, condition monitoring of equipment, performance analysis,optimization of load dispatching and instruction for the unit operation etc. In addition, the real-time historical database iHistorian of GE Fanuc Company and the supervisory configuration software iFIX are used as the software platform of SIS to realize system redundancy on network and software, thus assures the stable and reliable system operation.
