The invention discloses a power grid comprehensive visualization method based on multi-service system information fusion. On the basis of comprehensively organizing service flows and data models of links of an intelligent power grid, an information exchange bus crossing a production control region and a management information region is utilized to obtain relative operational and management information of systems such as a production management system (PMS), a distribution management system (DMS), an energy management system (EMS), an electric transmission and transformation equipment state monitoring system, a distribution network production quick-repairing commanding platform, a centralized video monitoring system, a marketing management system, an electricity consumption information acquisition system, a geographical information system (GIS), an intelligent district energy consumption management system, a residential area intelligent electricity consumption interaction and energy efficiency management system, an electric vehicle charging facility comprehensive monitoring and management system and a weather system, and furthermore, based on the relative operational and management information, the data is subjected to deep mining, analysis and comprehensive displaying. The power grid comprehensive visualization method based on multi-service system information fusion helps the production operational and management personnel to master the real-time running state of the power grid more comprehensively, visually and effectively.
