Research on GIS Topology Modeling of Distribution Network Based on Data Fusion

With the expansion and increased complexity of distribution networks, establishing a distribution network line model library has become an important means of accurately analyzing and simulating the distribution network. This article proposes a topology modeling method based on data fusion and GIS platform for distribution networks. By collecting and constructing a multi-source database of distribution network lines, combined with data fusion and dynamic routing methods, the rapid modeling of the distribution network topology model and the generation of update strategies are achieved. The article introduces how to construct the model on the GIS platform and proposes a network graph display optimization scheme. By combining hierarchical display and spatial indexing technology, the rendering processing speed is improved, providing effective support for distribution network planning and operation optimization.
