The Application of Data Warehouse and Data Mining Technology in Power System

In the past half century, the development of information technology, computer technology and network technology has deeply influenced the production and management of power system from all aspects. SCADA, EMS, GIS and other information systems appeared. But the existing information systems have some problems to be solved, such as data cannot be shared, the level of integration is low; vast amounts of data extract information characteristics are difficult; timely monitor and forecast of business is difficult. The electric power information factory based on data warehouse and data mining technology is the solution of the problems. This paper mainly studies the applications of the data warehouse technology and the data mining technology in power system. After introducing the subject background, this paper firstly introduces the overall architecture of information enterprises and factories, individual components and their mutual relations. The paper mainly expounds the decision support system, data warehouse and data mining technology.
