Time and space are the basis of the “strong smart grid”, which makes both the grid state and the accident closely related to them. Actually, there are more demands on emergency communication of different regions and parts. Focused on difficulties of situation fusion and weak presentation in the grid communication network, this paper proposes a distributed emergency communication system for electric power based on spatial, time, and situation fused big data. It designs an adaptive framework without relationships to services, proposes a heter-element reference for spatial and time big data. It achieves the transformation from different data into the same geo-coordinate. The classification basis of situation and plotting of grid emergency communication system is also formulated. The tests and simulations on ArcGIS and Linux demonstrate better performance in accuracy and lower data consumption.
