Research on the SCADA /EMS System Data Warehouse Technology

Data warehouse (DW) technology is an effective method to use the large amount data with complex correlation. This paper describes the structure of the DW of SCADA/EMS. The system is made up of enterprise application integration (EAI) node, real-time data process center (RTDPC), an active DW and management tools. Management tools take in charge with metadata, node configure information and system management information. Particular attention is paid to architectural topologies of successful implementation and the role of frameworks for EAI. The DW is an efficient and secure information exchange and storage platform of modern control center, data mining and decision support system
