In view of the lack of unified information model for distribution network data

the low quality of basic data

the large difference in demand for models

and the lack of practical application support

Hunan electric power grid promoted the construction of ubiquitous power internet of things to land in the field of distribution network

based on the unified information model of distribution network and with the goal of "maintenance at source and global sharing"

carried out the works such as standardized modeling

validation and governance of distribution network graphic model data

automatic and optimized mapping of thematic maps

interactive application with PMS2.0 system and distribution automation system

etc. to realize the significant improvement of the quality of the distribution network graphic model data and the online closed-loop management of the new investment and change process of the devices and gradually promoted the "one map of the whole network". Then the distribution network panoramic model with unified logic

clear backbone and clear hierarchy can be provided for each major of Hunan electric power grid

to fully support the core professional work construction and practical application such as comprehensive fault analysis and power supply service command

and effectively improve the fault handling efficiency and the power supply service quality level of distribution network.
