Abstract

As the installed base of substation equipment continues to grow, the capacity of primary equipment increases, and operating lifetimes extend, traditional maintenance-centered and periodic management approaches are no longer able to meet the combined requirements of fault-risk control, outage consequence mitigation, and operations-and-maintenance (O&M) cost containment. Focusing on the health management needs of primary substation equipment—represented by power transformers and gas-insulated switchgear (GIS)—the report proposes a data-centric, full life-cycle health management technical roadmap. It first identifies and extracts “state-value data” that can effectively characterize equipment condition, and then strengthens data aggregation, governance, and quality improvement. Next, in view of the differences between incipient/gradual faults and sudden faults, it develops a health-state assessment framework and models, enabling “one device, one period” personalized evaluation as well as event-triggered real-time assessment. Finally, it uses assessment and early-warning results to drive differentiated maintenance strategies, balancing reliability and cost-effectiveness. The report also reviews relevant domestic and international advances (e.g., PHM, HUMS, AHM, and AI-based diagnosis and prognosis) and outlines the application prospects of health management in reducing downtime and repair costs caused by sudden failures, improving O&M decision-making efficiency, and accelerating the digital and intelligent transformation of power-grid O&M.
