Core Viewpoint - The State Grid Fujian Electric Power Company has successfully implemented an automated self-healing system for its distribution network, significantly improving the reliability and efficiency of power supply recovery after faults [1][2]. Group 1: System Automation and Efficiency - The automated system allows for the entire process of fault recovery to be completed without manual intervention, achieving batch automatic power transfer within 5 minutes [2]. - The "full stop and full transfer" automation has increased the efficiency of power supply recovery, with an average transfer time of only 5.7 minutes, representing a 90% improvement in overall response efficiency compared to traditional methods [2][4]. - The company has achieved 100% coverage of automated feeders in urban core areas, with a total of 1,410 automated feeders optimized in Xiamen [2]. Group 2: Infrastructure and Technological Advancements - The company has completed the transformation of 400,000 distribution automation switches and built 1,150 intelligent visualized distribution rooms across the province [4]. - The automated feeder system now covers 91% of the province, with the capability for second-level self-healing in case of feeder faults [4]. - The company has installed 11,600 automated feeders, enhancing the monitoring and analysis capabilities of the distribution network [4]. Group 3: Emergency Response and Reliability - The automated system functions similarly to a human immune system, allowing for real-time monitoring and rapid isolation of affected areas, ensuring overall power supply stability [3]. - The company has successfully responded to 19 transformer station faults this year, restoring power to 86,000 customers in a matter of minutes [2].
