China has the highest electricity consumption in the world, and the safety of the power grid is crucial. At State Grid Jibei Tangshan Power Supply Company, Li Bingjun, a post-90s maintenance worker, uses AI to monitor the power grid and won the National May Day Labor Medal in 2026.

Li Bingjun graduated from Harbin Institute of Technology with a major in Electrical Engineering and works in secondary maintenance of substations. A few years ago, AI was just on the rise, and most people were still watching. It had already plunged into it. Master and national model worker Wang Wei has high hopes for him: 'The power grid is becoming increasingly complex, and it's hard to remember it with a human brain.'“

But AI is not our profession. I haven't touched the code before, so I silently write line by line if I can't understand it. If the model can't run, I start over and over again. More than 600 pages of notes, tens of thousands of lines of code, and over 100 models were tested by the first version of the power outage analysis intelligent agent, with an accuracy rate of only 50%.

He didn't give up. Staring at the screen every day to compare the code, translating the master's decades of on-site experience into logic that AI can understand. Nearly a year later, the new version of the intelligent agent was launched: it integrates fault, real-time, and historical multidimensional data, automatically generates a complete report within 5 minutes, and has a 100% accuracy rate for key information. Running over 200 reports in a month.

Now he has led his team to develop a portable safety intelligent emergency device, with economic benefits exceeding tens of millions, and customer characteristic analysis has been reduced from half an hour to three minutes.

My master has passed on knowledge to me from generation to generation, and I want to use AI to pass on this skill, so that more frontline workers can embrace AI.Editor/Cheng Liting
