State Grid Suqian: AI command system helps secure power supply during Typhoon Bavi

Tang Yuqiang of State Grid Suqian Power Supply Company used the AI-based power supply service command system for voltage inspection on distribution transformers when the system alerted him to an abnormal transformer voltage on July 13.

An on‑site check revealed a loose and overheating phase‑A terminal clamp. If left undetected, this could have damaged the terminal, caused transformer outages, or even sparked fires under extreme conditions — directly threatening electrical supply for two large enterprises and over 60 nearby households. Timely identification and repair prevented outages and ensured safe power delivery during the typhoon.

Tang said that during the typhoon, all staff remained on duty, and the loose‑terminal alarm system greatly improved their efficiency.

He added that with more than 6,000 distribution transformers across Sihong county, manual inspection would take at least a month per round — impractical amid severe weather.

The AI command system now allows personnel to head straight to designated locations, drastically cutting response time.

The transformer terminal‑loosening detection model was officially launched on the AI command platform on Jan 19. Since deployment, it has enabled rapid handling of 28 faults, saving roughly two hours per incident on average and cumulatively reducing downtime by over 56 household-hours.

During Typhoon Bavi alone, the system promptly detected and addressed two incidents that required replacement of distribution transformers due to terminal failures.

Proactively responding to the typhoon, State Grid Suqian leveraged this AI tool to maintain grid stability, demonstrating how intelligent monitoring can effectively complement manual efforts in extreme weather.

The system's success highlights the value of real‑time anomaly detection in safeguarding critical infrastructure and minimizing disruption for both industrial users and residential communities.
