Abstract:Electric power industry is an important supporting industry of national economy and national development strategy，large power data has become the core of the future development of electric power industry with the rapid integration and development of information technology and power grid construction,From the point of view of demand, processing and application of big data in electric power enterprises,this paper makes technical and theoretical research based on the whole process of actual business development, such as planning budget, power network operation, core resources, key processes, thematic monitoring and so on.Taking horizontal cooperative business application construction as a breakthrough, the mechanism of business application and technology coordination is constructed.Establish a unified data flow of "data is clean and transparent, model is unified, analysis is flexible and intelligent"for the whole business.Taking data demand as the direction and taking data depth mining, analysis and screening as the means, we can realize "the whole business cooperation, the whole process through, and the all data sharing".Through the comprehensive analysis of the big data architecture of electric power enterprises, we can strengthen the aggregation and integration of all business data, deepen the overall architecture management and control, and provide reliable technical support for the creation of world-class energy Internet enterprises.
