火电厂厂级自动化系统 (PAS)应由非实时管理的厂级管理信息系统 (MIS)和实时管理的厂级监控信息系统 (SIS)构成。SIS的目的是在对全厂各个机组、输煤、除灰等公用系统生产工况进行监控的基础上 ,实现经济目标控制下全厂的协调生产。建议SIS的网络结构 ,以以太网和FCS为基础继续发展 ,最终将整个电厂融入单一的以太网中。
Thermal power plant plant automation system (PAS) should be non-real-time management of plant management information system (MIS) and real-time management of plant-level monitoring information system (SIS) form. The purpose of SIS is to realize the coordinated production of the whole plant under the control of economic objectives on the basis of monitoring the production conditions of the common systems such as the whole plant, coal handling and ash removal. It is proposed that SIS’s network structure continue to evolve on the basis of Ethernet and FCS and eventually integrate the entire power plant into a single Ethernet network.
