Trends and challenges of substation O&M and inspection

Substations are crucial energy transmission nodes in power grids, responsible for power production, operation, and control. To ensure safe, reliable, and efficient operation, preventive maintenance inspections are conducted on substation devices to monitor their running status, detect problems, and address defects promptly. With economic development placing higher demands on power grid security, the grid's scale continues to expand, and new power technologies bring new challenges to substation operation and inspection.

Advancements in big data, cloud computing, AI, 5G communications, information security, and IoT offer technical assistance in building intelligent substations. Driven by digital technologies, power transformation services utilize data resources to enhance device status control, device management, and team operations, hastening the arrival of new intelligent production modes.
