ted manufacturing open system (CIMOSA) in ESPRIT plan of European Economic Community, Enterprise GRAI integrated methodology (GIM) of GRAI/LAP lab of Bordeaux University in France and Purdue Enterprise Reference Architecture (PERA) of Purdue University in . Almost all the models above are researched for dispersed manufacturing and the target model is centralized at integration of CAX (CAD/CAPP/CAM/CAE), PDM and MRPII. Integration of flow enterprise is in the ascendant now all over the world. Flow enterprise is similar to dispersed manufacturing on some sides and quite different on other sides. For flow enterprise, CIMS should be called Computer Integrated Production System (CIPS) or integration automation system for whole plant Research on CIPS of power plant is almost a blank space for power enterprises in most countries. Definite research papers on power system are about integration from power generating to power delivering. Innovation of power enterprises in China creates condition for implementation of CIPS in power plantsIn order to enhance the whole management level and operation efficiency and to strengthen the market petition of power plant, all famous control corporations all over the world have made progresses and have had experiences in developing integration of management and control of power plants. These latest harvests have been applied in some modern power plants. It is gradually forming an important level of integration of management and control between traditional DCS and MIS. The system could optimize management of real time process of the whole plant. On one hand, its functions are to realize operation optimization, load distribution, economy analysis, equipment diagnosis, equipment status maintenance and equipment life management, etc. On the other hand, it could transmit data to the management system of MIS of business, archives, OA and so on. In the physical configuration, this level lies between DCS with high precision, high speed and high reliability and MIS which doesn39。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.
