Core Viewpoint - The successful installation of the DTU (Distribution Terminal Unit) marks a significant advancement in the automation level of the distribution network for the State Grid Urumqi Power Supply Company, enhancing operational efficiency and safety [1][2]. Group 1: Installation and Safety Measures - The company completed the installation of the DTU on the 10 kV Tianhe Line 1 Ring Network Cabinet while energized, representing the first such operation for the company [1]. - To ensure safety during the live operation, the company organized a thorough site survey and developed a detailed construction plan along with secondary safety measures [1]. - Workers conducted a site re-inspection before installation to confirm equipment positioning and power access, and they prepared heat prevention supplies due to summer conditions [1]. Group 2: Operational Efficiency and Benefits - The newly installed DTU features remote monitoring, fault location, and automatic isolation capabilities, significantly improving fault response times [2]. - The time taken to isolate fault sections has been reduced from minutes to seconds, greatly enhancing the restoration of power to non-fault areas [2]. - The company plans to install a total of 107 DTUs this year, aiming to further enhance the self-healing capabilities of the distribution network [2].

Core Viewpoint - The construction of an automated distribution network in Fushan County marks a significant advancement in smart grid technology, enhancing power reliability for economic development and public electricity needs [1][3]. Group 1: Automation and Technology Implementation - The company achieved a 95% effective coverage rate of "feeder automation" in Fushan County, indicating the successful integration of smart distribution network technology in mountainous areas [1]. - The installation of 70 intelligent branch segment switches on top of the existing 150 intelligent switches has improved fault detection and response times, reducing repair times by 90 minutes and minimizing the number of affected households by 180 [4]. - The automated system can isolate fault sections within one minute, allowing for uninterrupted power supply to non-fault areas, resulting in a "zero perception" experience for users during outages [4]. Group 2: Performance Metrics and Impact - The online rate of various distribution automation terminals reached 96.52%, with a 50% reduction in overall outages and a 43% decrease in branch segment outages [4]. - The average outage duration per household decreased by 52%, showcasing the effectiveness of the automated equipment in enhancing grid reliability [4]. - The automated distribution network supports the integration of 600 megawatts of renewable energy capacity in the county, strengthening the grid's ability to accommodate new energy sources [4]. Group 3: Future Plans - The company plans to continue advancing the automation of the distribution network, focusing on digitalization and practical applications to further enhance fault detection and reduce outage times [5].
