火电厂的SIS建设及实时数据库平台的选择

Construction of SIS and selection of real time database in fossil fuel power plant

具体论述了电厂厂级监控信息系统(简称SIS)的系统架构和SIS与管理信息系统(简称MIS)的连接方式,指出SIS和MIS应采用独立的网络进行连接以提高安全性和可靠性.同时分析了SIS建设中实时数据库平台的选择原则,包括数据存储效率、系统访问结构、接口技术、数据缓冲和容错功能等.同时还讨论了SIS中各项高级应用应该实现的具体功能,为电厂开展SIS建设提供了参考.

System structures of supervisory information system (SIS) and its connection mode with management information system (MIS) were discussed in detail. It was suggested that the network of SIS and MIS should be separately connected to improve security and reliability. The selection principles of real time database were analyzed which include data storage efficiency,access mode of system,interface technique,buffer function and fault tolerant function and so on. Also specific functions in SIS are described so as to apply to construction of SIS in fossil fuel power plant.
