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 general quality control system in power plant. According to the hierarchy model, the function system of management and decisionmaking level is Management Information System (MIS), the function system of supervisory analysis level is Supervisory Information System (SIS). Unit control level and function group control level form lots of process Automation Systems (AS). There is a corresponding mapping relationship between the hierarchy control view and function view in power plant. The function view of TPPCIPS is referred to Figure 24. The Mode of Implementation of TPPCIPSThis paper presents a mode of implementation of TPPCIPS based on life period. See Figure 3. Referring to the conventional three stages of life period, this paper puts forward a mode of five stages from system analysis, system design, system implementation to system maintenance, system optimization. It is a closed loop way instead of conventional opening loop way. It not only introduces general theory to thermal power plant, but also extends the conventional three stages theory to an important technique base of implementation of CIPS. System analysis, system design and system implementation are important stages of implementation of TPPCIPS, system maintenance and system optimization are also necessary to enhance the operation level and optimize the system.Work and fruits of each stage of life period are as following:(1) System analysis stage: to set up enterprise demand analysis model based on operation investigation, actuality analysis and demand definition. This model should include the primary concept models of organization view model, resource view model, function view model and information view model. All these models are main input and design principle of system design.(2) System design stage: to modify function configuration and organization configuration according to the concept models and relative system analysis document, to perfect organization view model, resource view model,
