【正文】 產(chǎn)系統(tǒng)( CIPS)或集成自動化系統(tǒng)中，大多數(shù)國家的電力企業(yè)對發(fā)電廠計算機集成生產(chǎn)系統(tǒng)CIPS進行整套裝置的研究，幾乎是一個空白。層次結構維包括管理信息系統(tǒng)（MIS）、監(jiān)控信息系統(tǒng)（SIS）和過程自動化系統(tǒng)如分散控制系統(tǒng)（DCS）等；視圖維包括功能視圖、資源視圖、組織視圖和信息視圖；生命周期維包括系統(tǒng)分析、系統(tǒng)設計、系統(tǒng)實施、運行維護和優(yōu)化提高等五個階段。t affect safe operation. This system is an important research item now, which is called Supervisory Information System (SIS)To set up an integration model for power plant, especially large size thermal power plant could bring evident economic benefits to power plants. This paper based upon the thorough study of it, will put forward a three dimensional space architecture which is called Computer Integrated Production System for large size thermal power plant (TPPCIPS).2. Hierarchy Model of TPPCIPSHierarchy model is a structure description of CIMS, it is a base of design and realizing CIMS. Large size thermal power plant TPPCIPS is an industrial integration automation system which gives priority to process control and supervisory analysis management. Referring to Purdue Reference Model, this paper puts forward a hierarchy model with five levels and two sustaining systems. See Figure 1. Five level models and their main functions are: Field control level: this level is the base automation level of power plant, which controls the process directly including various measurements, instruments and actuators.Function control level: this level is to control the technological system of each functional group level, such as bustion control system, feed water control system, steam control system etc. in the DCS of main power building.Unit control level: this level is the workshop machine hall control level of power plant, which controls each unit and balance systems of power plant such as DCS of each unit, PLC and SCADA of auxiliary mon systems etc.Supervisory analysis level: this level is the real time supervisory level of whole power plant, which is to realize operation optimization, load distribution, economy analysis, equipment diagnosis, equipment status maintenance and equipment life management etc.Management and decisionmaking level: this level is the management information level of whole power plant, which is to realize business running management, finance management, resources management etc. norealtime management3. Function View of TPPCIPSAccording to the latest research fruits of flow enterprises, function view of CIPS includes management information system, quality control system, process automation system, dynamic supervisory system, puter network and database management system (DBMS).There is not
