Renewable energy plays a pivotal role in modern energy systems, serving as a cornerstone for energy security, sustainability, and cost efficiency while delivering substantial environmental benefits. From an ethical standpoint of preserving planetary resources to addressing tangible economic and operational concerns, the transition to renewable energy generation has become imperative. Globally, nations are increasingly scaling up renewable energy integration, with several achieving full reliance

Traditional transformer operation and maintenance (O&M) relies on periodic inspections and corrective repairs, suffering from three core pain points: blind maintenance, high costs, and slow fault response. It fails to capture real-time degradation trends of internal multi-physical fields, leading to sudden faults that trigger large-scale power outages, while keeping labor and spare parts costs at a persistently high level. With the deployment of UHV DC interconnection and the high-density ur

1.Industry Background1.1 Industry BackgroundWith the advancement of global energy structure adjustment and the "dual carbon" goals, the energy conservation, intelligence, and safety of power equipment have become important tasks for power grid enterprises and industrial users. A large number of medium-voltage power transformers put into operation in the 1980s and 1990s still play a crucial role in power supply in power grids, factories, and industrial parks. However, the current IEC 60076 series

Project BackgroundAgainst the backdrop of global energy transition, issues such as low short-circuit ratio (SCR), subsynchronous oscillation (SSO), and harmonic pollution caused by the grid integration of high-proportion wind and photovoltaic power have posed severe threats to the operation of high-voltage transformers and the safety of power grids.Core Pain PointsSevere Voltage Fluctuations: Rapid changes in the output of renewable energy sources lead to frequent voltage limit violations at tra

IntroductionWith the continuous expansion of global energy layouts to alpine polar regions, tropical coastal areas, arid deserts, and high-seismic-intensity zones, the operational risks of high-voltage transformers under extreme environments have become increasingly prominent. Alpine/low-temperature and low-air-pressure conditions will cause an increase in insulating oil viscosity and a decline in cooling capacity; high temperatures and sand dust will weaken heat dissipation and accelerate compo
