As the 15th National Games of China opens on Nov 9, the Zhuhai Power Supply Bureau of China Southern Power Grid continues to drive the digital, ecological, and intelligent transformation of power supply, injecting strong momentum into the smooth running of the 15th National Games.
Smart monitoring powers "command center" to guarantee electricity
At the Zhuhai Hengqin International Tennis Center, various test events have been in full swing since June this year.

"We've equipped the power supply lines inside the competition venues with 'sports wristbands'," said Yang Kaifan, Manager of the Safety Supervision Department (Operation Risk Monitoring Center) at the Hengqin Power Supply Bureau under Zhuhai Power Supply Bureau. "These wristbands can collect and upload real-time operating data, instantly detect abnormal signals, and send feedback to the backend system. This allows our maintenance team to identify problem areas with precision, significantly improving the efficiency of routine inspections and fault responses."
The so-called "sports wristbands" refer to the "Dianhong" flexible clip, a new technology to be used by Zhuhai Power Supply Bureau for the first time during the 15th National Games.

"In the past, we had to take turns to conduct scheduled inspections," Yang explained. "Now, the system sends automatic alerts, allowing our personnel to focus more on analyzing issues and fixing faults." As a result, the time needed to locate low-voltage faults has been reduced from one hour to just 15 minutes, and operation and maintenance efficiency has increased by 50%.
Power secured with multi-layer protection, outdoor venues self-heal
"Outdoor events usually have relatively small electrical loads, but the real challenge lies in the tight setup schedule, which places higher demands on on-site inspections and planning," said Yuan Haosen, Deputy Director of the Urban Power Supply Office of Zhuhai Xiangzhou Power Supply Bureau.

Power supply staff members monitor the operation of the competition venue's electrical equipment in real time through the "Power Supply Monitoring Map" system.
The cycling events of the 15th National Games were held entirely outdoors. To address the unique challenges of temporary outdoor power use, the Zhuhai Power Supply Bureau introduced an optimized solution featuring multiple distribution points and enhanced backup power systems.
"We divided the power supply lines in the event area into three independent modules, so that any abnormal situation in one zone would not affect the others," explained Yuan. "For example, if a line failure occurs in the stage area, causing a power outage, the broadcasting and check-in areas will remain unaffected. This setup ensures the smooth operation of the event to the greatest extent possible."
In addition, during the National Games, the power supply team will optimize the grid structure through a "minimal operation mode", isolating the event's power loads from other users, essentially adding an extra "protective shield" around critical equipment.
Stable power from Guangdong to Macao backed by protective network
As a key hub for power transmission from the Chinese mainland to Macao, the Zhuhai Power Supply Bureau has leveraged its independently developed Dianhong IoT operating system to guarantee a stable power supply. At key substations and along power line corridors within the Guangdong-Macao interconnected power grid, various AI-powered devices made in China, such as quadruped robots, are being deployed. These devices allow for remote operation and monitoring, ensuring a stable and reliable power supply from the Chinese mainland to Macao during the 15th National Games.

In the run-up to the National Games, the Zhuhai Power Supply Bureau also pioneered the use of sub-meter-level satellite remote sensing technology to inspect transmission line corridors.
"It's like having a 'clairvoyant eye' in space," explained Liu Jinhu, a specialist from the Transmission Management Office of the Zhuhai Power Supply Bureau. "By scanning all transmission lines across Zhuhai via satellite, the system can detect potential risks early, giving maintenance teams extra time to respond on site."
With this "space-air-ground integrated" inspection technology, the Zhuhai Power Supply Bureau has completed a comprehensive inspection of the power grid in Zhuhai and the power supply from the Chinese mainland to Macao ahead of the 15th National Games, enabling early detection, intervention, and timely handling of potential risks.

"Whether it is the digital monitoring at the Tennis Center, the multiple backup routes for power supply at the cycling venues, or the satellite-based inspections and voltage regulation of the main power grid, the core objective remains the same: to ensure uninterrupted power supply with cutting-edge technology and the strictest standards," said a spokesperson from the Zhuhai Power Supply Bureau.
