This paper presents an implementation of a web-based distribution network GIS platform that seamlessly integrates distribution system feeder GIS monitoring with the system model file layout, fault current analysis, and coordination simulation functions. Based on the design concept and technical route of the grid planning. This work introduces GeoTopo-Net, a novel multi-stage pipeline that automatically groups power distribution equipment into topologically meaningful components. Predict. In the modern era of smart grids, integrating advanced Geographic Information Systems (GISs) with protection coordination functionalities is pivotal for enhancing the reliability and efficiency of distribution networks. The geographic approach, through ESRI® GIS technology, allows us to view, query, and understand data in many ways. We. Duquesne Light Company (DLC) is located in Pittsburgh, Pennsylvania.
