Abstract


Power system scheduling department is one of the core sectors , with a high degree of information , a huge amount of data , the associated departments and business and more features , power scheduling has been the focus of enterprise information construction . But information technology early, as the level of awareness is low , the lack of long-term information technology planning , information systems led to this stage evolved into highly distributed , heterogeneous systems , the formation of a large amount of information \Information \As a specialized data warehouse for decision support data storage system that can change the data storage model, data mining and other analytical methods to provide strong support . Construction scheduling data warehouse stage for the power of information technology in enterprises solve problems , improve the enterprise information system data layer, to support the further development of advanced application scheduling system has important significance. Data warehouse system for the main problems in the construction of this paper under the Electricity enterprise data warehouse project planning and consulting of practical experience , summed up the construction of the power system data warehouse set of standardized methods . Paper first analyzes the characteristics of the data warehouse system implementation , emphasizing the information resource planning in the data warehouse construction in the important role of information and summed up the characteristics of electric power enterprises and basic methods . Logic modeling is a data warehouse is one of the most important work , this paper analyzes the characteristics of the dimensional model is proposed through the object model into a dimensional model approach , and according to the actual needs of power dispatching key decisions to complete the theme dimension model. For data staging , paper, based on CIM / ECIM achieve universal integration platform , and proposed integration platform based on a common data warehouse staging strategies . Paper concludes on the basis of the data warehouse system data mining and other data analysis methods in power enterprise applications, and in accordance with the actual needs of the dispatch department proposed construction of information systems planning, full use of the data warehouse system specified direction.
