Power companies facilitate post-Spring Festival return to work

As businesses reopened after the Spring Festival holiday, power companies kept monitoring key transmission lines to ensure reliable electricity supply.

Using the PMS3.0 system, operators with the State Grid Jiaxing Power Supply Company carried out repeated remote inspections of the line to identify potential risks. Through an emergency response mechanism integrating remote monitoring, intelligent warning, work-order dispatch and closed-loop handling, potential hazards on power lines serving major enterprises can be detected and addressed in a timely manner.

With industrial parks gradually resuming full operations, electricity demand has been rising steadily. The 220-kilovolt Xingli 23T0 line provides a dedicated power supply for the Alibaba Yangtze River Delta Intelligent Computing Center, making supply reliability crucial.

To ensure stable operations during the key period of work resumption, the monitoring center has relied on remote visual monitoring devices installed along the line. The system can automatically identify and issue alerts for eight categories of hazards, including fire risks and foreign objects, enabling staff to track the conditions of transmission corridors dozens of kilometers away without leaving the control room.

"In the past, we had to travel to the site and inspect the line section by section," one member of the monitoring staff said. 

"Now, we can review photos captured by the system and ensure no potential hazard is overlooked."

The company has also expanded the use of intelligent equipment such as drones and visual monitoring systems, forming an integrated operation model that combines aerial inspections, centralized monitoring and field inspection stations.

During the work resumption period, the monitoring center has conducted two rounds of remote inspections of key transmission lines per day, with the smart monitoring system ensuring power grid reliability.
