The Application Of PI Real-Time Database For Power Enterprises Informatization

Along with the development of informatization, power enterprises applied management information system and developed overall information management systems which can control all plant lifecycle in order to use the advantage of information process to solve overall management for plant management and devices management. When it deals the devices management, some problems were found such as no real-time data communication between devices, the difference data standard for each devices and so on. By building a real-time performance management platform, the management and controlling of an enterprise will be unified. The existing problem of information bottleneck will be solved. Hence it is vital importance for the information construction of power enterprises.PI real-time database is a real-time series database, has the function of data collection and management. It has many advantages such as enterprise level data platform, prototype store data, fine opening to the outside world and diversify the mature interface and so on. So it can realize plant management and device control unifying and improve the plant management.Firstly, this paper discusses the principle, functions and characteristics of the plant information system. Then integrating the really apply problem of Xiaoshan Economic & Technological Development Zone Thermoelectricity co., Ltd, it using OSI standard interface for PI, OSI standard interface for OPC and customized interface these three methods realize the goal of data gathering and unification interface. After this, it introduces that how to resolve the real problems in the plant, such as providing chart of the flow of arts and crafts, the application of reports, the calculation of main economic guidelines, the alarm management, the on-line analysis of the wearing down features of the equipment, and the controllable loss, working conditions, the optimizing guiding of the equipment and etc. Then it introduces the application effect of PI real-time database in the plant. At last, it introduces some achievements of using the PI real-time database system in the plant and some disadvantages of the PI real-time database are also discussed.
