Discussion About Integrated Operation and Maintenance Framework for Information and Communication Network of Power Grid

This paper comprehensively analyzed the development of the smart grid, combined with the latest ICT technology development results, demonstrated the important role of information and communication network for new applications in smart grid, put forward the integrated framework of operation and maintenance which is based on resource integration, supported by standardize processes and centered by an integrated evaluation. This paper points out the key technical problems such as the resource model, the monitoring data fusion, intelligent alarm indicator evaluation system, and running state assessment in the building of operation and maintenance system for the integration of smart grid information and communications. The key technologies are pointed out in different aspects: resource model, intelligent warning, evaluation system and visualization.
