As the peak summer season of electricity demand approaches, to enhance the reliability and safety of power supply, the State Grid Nanyang Power Supply Co., Ltd. has strengthened night inspections and developed new operation and maintenance models to fully ensure grid security.

Given that equipment is prone to overheating under high-temperature and high-load conditions, the company has carried out meticulous inspections of substation main equipment and connection points of heavily loaded lines during peak nighttime electricity consumption hours. Using infrared imaging technology and historical trend analysis of equipment operation data, maintenance personnel can accurately detect potential defects. Mobile inspection terminals allow real-time data uploads and smart alerts for anomalies, forming a 24/7 monitoring network for power equipment.

In terms of operational mechanisms, the company has integrated expert teams from substation, transmission, automation, and other specialties into a joint inspection group to ensure on-site assessment and joint resolution of complex hidden risks. Urgent issues are addressed immediately, while general potential risks are incorporated into the equipment’s full life cycle tracking system.

Additionally, the company has improved coordination between meteorological early warnings and grid dispatching. Leveraging its intelligent monitoring platform, it tracks real-time load fluctuations and dynamically optimizes grid operation. It has also conducted equipment load testing and additional preventive measures to ensure stable operation under extreme weather conditions.

Looking ahead, the State Grid Nanyang Power Supply Co., Ltd. will continue to strengthen grid operation management, increase inspection frequency and scope, and eliminate weak points and hidden risks in infrastructure to ensure a safe and reliable power supply for customers in its jurisdiction.
