To implement and test the "second-level order acceptance, minute-level on-site arrival, and time-limited power restoration" response mechanism in real-world scenarios, the Yandu Power Supply Service Center of State Grid Yancheng Power Supply Company recently activated its emergency response plan for severe weather, following the principle of "restoring power first, then investigating the cause." From the system's automatic assessment of the power outage to the precise delivery of work orders to the on-duty mobile phones within the center, the entire process was transmitted to the "nerve endings" of the digital power supply service command platform within tens of seconds, demonstrating the true practical value of emergency repairs and power restoration.
Under normal circumstances, the leakage current value of the integrated protection device in the distribution area soared to 4800 mA, and conventional megohmmeters could not quickly locate the specific leakage point in a humid environment. The Yandu Power Supply Service Center of State Grid Yancheng Power Supply Company adopted the classic elimination method of "testing the meter and switching off the circuit breaker for each household + alternating verification" to investigate. They first deactivated the leakage protection tripping function to restore power supply to the public transformer, and then contacted the night shift user to temporarily disconnect the faulty circuit. The proactive strategy of "restoring power first and then investigating" fulfilled the hard constraint on the number of households affected by the power outage, forcing the frontline staff to embed the awareness of "speed" into every order received, every power restoration test, and every line patrol.
"Property rights have boundaries, but service has no boundaries." The Yandu Power Supply Service Center of State Grid Yancheng Power Supply Company has always advocated taking a step forward in extending services beyond the meter box. This includes assisting in the investigation and notification of potential hazards on the user side that are missing or have expired home protection devices, replacing new lines, re-insulating the insulation, testing the home protection devices to ensure they function normally, completely eliminating potential hazards and forming a closed-loop defect elimination file, and finding old aluminum wires with hidden hazards. The average on-site arrival time has been significantly accelerated, which not only reduces the probability of cascading trips caused by user internal faults, but also incorporates "People's Electricity for the People" into every greeting when knocking on a user's door.

Meanwhile, the Yandu Power Supply Service Center of State Grid Yancheng Power Supply Company has integrated intelligent public transformer monitoring terminals, power consumption information collection and distribution network emergency repair command platforms to achieve "all-round" real-time monitoring and automatic alarm of medium and low voltage equipment faults. It has implemented the principle of "restoring power first and then repairing", promoted the installation of end-point home protection, established an active early warning list for transformer areas with frequent leakage and abnormality, and incorporated the average fault repair time into the monthly key performance indicators of power supply stations from the institutional level. After filtering false alarms, the system automatically generates active repair work orders and pushes them to the handheld terminals of the nearest stationed personnel, which significantly reduces repair time and wasted time.
Therefore, we must emulate the State Grid Yancheng Power Supply Company's Yandu Service Center by comprehensively completing the inventory of grid-based stationed materials and flood prevention preparedness for the more than ten township power supply stations under its jurisdiction. We must implement a "one-station-one-policy" management system for low-voltage and frequently tripping transformer areas, and disseminate information on home electrical installation and safe electricity use through WeChat groups for "village-network co-construction." Only in this way can we proactively mitigate the seasonally high risk of leakage trips and fulfill our unwavering commitment to "second-level response" to restore power.
