State Grid Zhenjiang applies intelligent system to ensure power supply

At the upgrading and renovation site of the 10-kilovolt Rongzhuang Line's Shizhuang Branch Line, State Grid Zhenjiang Power Supply Co (State Grid Zhenjiang) innovatively deployed an intelligent management and control system to handle line fault diagnosis and optimize power load upgrades, thereby enhancing the region's power supply capacity for the upcoming summer peak period. Since the system was put into use, the fault isolation time in the pilot area has been reduced from 20 minutes to less than two minutes, the average customer outage duration has decreased by 90 percent year-on-year, and the power supply reliability rate has risen to 99.99 percent.

In the past, localized line faults often led to widespread blackouts across entire lines, and fault detection relied entirely on manual on-site inspections, which were time-consuming and inefficient. The new system functions as an "automatic line protection device", capable of monitoring line operations in real time 24/7 without any manual intervention. Once a partial fault occurs, the system quickly identifies the issue and automatically isolates the faulty section, ensuring a stable and continuous power supply to surrounding lines, minimizing the scope of outage impact, and safeguarding reliable electricity for residents, businesses, and industrial users.

State Grid Zhenjiang will continue to promote the application of intelligent technologies, further enhance emergency response capabilities for power supply, and make every effort to ensure the safe and stable operation of the power grid during the summer peak season.
