大型火电厂厂级网络总体设计和应用

介绍了进行大型火电厂厂级网络互联和集成总体设计的工程实例，提出了在工程设计阶段将火电厂生产过程中不同操作系统和不同软硬件平台的监控系统进行互联，应用以太网交换技术、光纤技术、时钟同步技术、客户/服务器(Client/Server)技术等手段，统一互联系统的各层网络通信协议，实现电厂主要生产过程各类实时信息的高度集成和发电负荷自动分配，提高电厂的综合自动化水平和现代化管理水平。

OVERALL PLAN AND APPLICATION OF THE PLANT LEVEL NETWORK IN A LARGE THERMAL POWER PLANT

This paper introduces an instance of an actual project of the overall plan of the plant level network interconnectionand integration in a large thermal power plant. To interconnect DCS/DAS/SCADA and MIS with different operation systemsand hardware/software platforms in the phase of project design is presented. Multiple techniques of Ethernet switcher.optical fibers, time synchronization and Client/Server etc are used to unify each level's network communication protocol of theinterconnected system. Therefore the high integration of all kinds of real--time information of plant and the automatic loadallocation for the generator can be implemented, and the degree of integration automation and modern management of thethermal power plant will be enhanced to a higher level.
