Abstract

Focusing on ultra-high voltage backbone grids

the application of large model technologies in this field is reviewed. First

the challenges faced by high-voltage direct current (HVDC) systems in achieving secure

stable

and efficient operation and maintenance under the energy transition are elaborated

and the solutions provided by large models are clarified. Second

the key characteristics of HVDC systems and the fundamental principles of large models in smart grids are summarized

with a focus on key technologies tailored to HVDC applications

including the construction of equipment knowledge systems

lightweight modelling of converter stations

and data-secure collaborative architectures. Then

through practical case studies

the applications and effectiveness of large models in HVDC fault diagnosis and prediction

operational evaluation and dispatch

and asset management are illustrated. Finally

the issues associated with large model applications

such as data quality and security

interpretability

and computational costs are analyzed

and future research directions and prospects are discussed. The study shows that large models can facilitate the transition of HVDC operation and maintenance from reactive repair to predictive maintenance

and enable the evolution of dispatching from experience-based decision-making to intelligent decision-making

which is of great significance for ensuring the safe and efficient operation of HVDC systems.
