State Grid Zhenjiang Power Supply Company upgrades intelligent robot system to ensure grid security

At the Maofeng 110 kilovolt substation in Jurong, Zhenjiang, Jiangsu province, an intelligent robot that had undergone hardware and software upgrades successfully completed a comprehensive condition assessment of the substation's equipment on Nov 13. By accurately measuring equipment temperature and collecting operational data, the robot intelligently analyzed the information to identify the operating status of multiple key devices. This provided robust technical support for the safe operation of the power grid during the peak winter demand period.

The upgrade equipped the robot with a more sensitive infrared temperature measurement system and multi-dimensional data collection devices, enabling round-the-clock monitoring of equipment conditions. Through its built-in intelligent analysis platform, the robot can promptly assess equipment health and accurately identify potential defects, significantly enhancing early warning capabilities.

"Previously, we had to inspect equipment temperature and data on-site one by one. Now, the robot not only automates these tasks but also provides early warnings through data analysis," explained an on-site worker. "It's like having a tireless 'diagnostic specialist' at the substation, allowing us to detect potential equipment issues earlier and take preventive measures in advance."

Since the deployment of intelligent robots, inspection efficiency has increased by approximately 40 percent, and the time required for a single equipment assessment has been reduced from two hours to just 30 minutes. This has freed up about 50 percent of on-site workforce. During the peak winter demand period, the robot measured the temperatures of over 40 pieces of equipment across multiple substations and identified and warned of seven abnormalities. This has not only significantly improved the reliability of grid operations but also reduced on-site operational risks by about 35 percent, enhancing the grid's emergency response capabilities and power supply reliability during peak winter demand.
