Research on Wide-area Distributed Power Quality Data Fusion Technology of Power Grid

With the advancement of the "big operation" system construction, the online monitoring system for power quality has been integrated, and various power quality data have been incorporated into relevant organizations for unified management. Power quality management has a larger range of data, more types, and higher frequency. It needs to realize the unified storage management and efficient access of massive heterogeneous power quality data for the characteristics of data applications and the collection and aggregation of these effective data. This paper proposes a new type of grid wide-area distributed power quality data integration architecture, which is designed for multi-source, heterogeneous, distributed data integration technology and wide-area distributed data storage technology to solve the big data source problem and realize the sharing of power quality data information of the whole network.
