Research and practice of integration of information in power dispatch center

For different computer technology and development practice during periods, information systems are often isolated with each other in power dispatching center. Shares of information resource have been proved to be difficult and expensive. The two typical data resources, online EMS data and offline data are analyzed. The technology of integration of the two data sources is researched and developed. Integration of several online/offline data at one time is supported in the method. Normal variety of power grid data is adaptable. With simple manual maintenance, abundant output could be shown by graphics or data table visually. By applying in the state power dispatching center, it is verified that the technology of data integration is feasible and improves the accuracy of the input data for advanced applications, thus make the result more reasonable and reliable.
