Core Viewpoint - The implementation of a digital "cloud map" system for distribution network equipment by the State Grid Yong'an Power Supply Company has significantly improved operational efficiency and fault response times in the region [3][4]. Group 1: Operational Efficiency - Since the launch of the digital "cloud map" system, the operational efficiency of Yong'an's distribution network maintenance has increased by approximately 50% [3]. - The time taken to address faults has been reduced by nearly 40%, from an average of 2 hours to just 15 minutes [4]. Group 2: Digital Transformation - The digitalization initiative addresses long-standing issues such as scattered equipment information and difficulties in locating devices, enhancing the management of distribution network equipment [3]. - The project began with a focus on the Yannan area, where a detailed survey of 65 key points was completed in 7 days, leading to precise equipment positioning [3][4]. Group 3: Comprehensive Mapping - Over a six-month period, the digitalization team successfully collected data on 660 distribution substations, 292 ring main units, 278 pole-mounted switches, and 302 transformers, creating a comprehensive "cloud map" of Yong'an's distribution network [4]. - The mobile terminal access allows maintenance personnel to view real-time photos, equipment records, repair logs, and navigation routes, facilitating a more informed and efficient response to issues [4].
