Large Thermal Power Plant Operation Optimization Control System

As economy developing, the situation of Power Supply and Power Request is changing from buyer's market to seller's market. The innovation of China power system is prompting changing the ideas. In the running of units of power plant, managers care more and more about how to improve the efficiency of Units to lower down the cost and protect the equipment. The Optimizing Control System of Super Power Plant is a powerful tool to actualize the aim for the managers.The paper is from this aim and based on the researching of internal and overseas different kinds of Optimizing Control System of Super Power Plant (OCS). It expatiates its background, system specification, system applying result of economic efficiency and analyze the importance of using this system for Power Plant.In this paper detailed statements of the pragress in making a Optimizing Control System of Super Power Plant and equipment monitoring are presented, deep analysis to the system designing, function analysis, data dealing and module compiling is giver also..The system is embedded software, working on the WDPF II control system of Westinghouse Corp. of USA and communicating to the control system real time, calling the global database, using some tools of WDPF system. In order to improve OCS working efficiency, we have to research the WDPF control system constructions, network structure, data type, database structure, communication mode, system tools applying and so on. So OCS uses the WDPF II resource as possible as it can in developing program. Because of the OCS running on the Soaris UNIX system of SUN workstation, the OCS has to be developed by specific OpenLook C++ language of SUN. Although this language is lack of Visual Development Envieronment, it is objected programming feature, has e rich classes of XVIEW to develop beautiful interface, operation easily and powerful UNIX software.The OCS is a high-level technical management system. It is a combination of modern computer control system and classical calculation method. The OCS's characteristic are powerful calculation, nicer interface, deep power plant running background, international energetic calculation method and intelligent computer based on original Power Plant control system.
