A Distributed Three Layer Topology Analysis Method Based on Graphx and Implementation for Medium and Low Voltage Distribution Network Topology Analysis

The distribution network structure is complex, the medium and low voltage equipment model is large, and a long time-consuming topology analysis. How to realize the fast and accurate topology analysis of the large data volume model has become the key to realize the advanced application analysis of the distribution Internet of Things cloud master station and the smart distribution network. Aiming at the problem of cumbersome topology analysis caused by the huge amount of data in the distribution Internet of Things cloud master station, this paper proposes a distributed three-layer topology analysis method based on GraphX, which uses the underlying static topology service, the middle layer dynamic topology service, and the upper layer application analysis. Three-layer topology structure, and distributed analysis method based on GraphX, using Unicom area block method, using Unicom area as a unit to analyze and process the topology change process, and realize fast reading and writing through HBase distributed storage using read-write separation method Functions, and provide micro-service calling interface to provide upper-level application analysis methods. It has been verified that the distributed three-tier topology analysis method based on GraphX is fast, efficient, and has great practical value.
