Abstract

In this paper, the generation technology of distribution network digital twin scene based on multi-module data fusion is studied. Firstly, multi-module data fusion is carried out in complex dynamic operating environment of distribution. Aiming at the deficiency of constructing digital twins from a single model source, various digital model resources in distribution link are collected and integrated to support the construction of hierarchical digital twin model of distribution network. The second step is to carry out the multi-source comprehensive reconstruction and entity hierarchical processing of the distribution network, establish the multi-source digital model of the universal distribution network equipment, and realize the global and local multi-level and multi-scale model display of the distribution network environment on the basis of comprehensive reconstruction; The third step is to configure the digital twin spatial mapping based on the distribution network's panoramic data fusion to realize the panoramic mapping between the real image, spatial coordinates and equipment monitoring data and the digital twin model, as well as multi-layer semantic information embedding such as equipment, region and job, forming the corresponding characteristics of multi-block, multi-level and multi-type digital twins. Finally, the distribution network panoramic digital twin model is dynamically updated to realize the projection of various real-time perception data to the digital twin, and the digital twin is updated synchronously and grown dynamically.
