Abstract: Abstract:The current general graphic platform can not satisfy the requirement of smart substation in integrated information processing. A new graphic platform based on the standards IEC 61790 and IEC 61850 was developed. Many functions are integrated in the new platform, which include the unified modeling of graphic model library of primary and secondary equipments, the integrated primary and secondary equipments mapping access components, the integrated configuration tools, the topological analysis and coloring based on CIM package and so on. The platform can be used to monitor the power grid operation status and the equipment operation data. By the platform, the power system information integration and modeling technology sharing can be realized. In addition, the remote browsing of the state grid and the source side maintenance of the China Southern Power Grid can be realized. The equipment graphic primitive layermanagement function and the advanced plugin component management function were integrated. The embedded threedimensional figure display function was added. The integration level and the operation and maintenance level of the system were raised. The system was put into trial operation successfully in a smart substation in Ningxia.
