Abstract: This research focuses on studying the strategy of technology-driven overhauls based on the asset wall, with a specific emphasis on aging equipment in the power grid.In recent years, with the rapid development of China's economy, investment in the power grid has been continuously increasing, leading to a continuous expansion of the physical assets in the power grid. At the same time, the tasks of operating, maintaining, and upgrading the power grid have become increasingly important. Scientifically planning the scale of the power grid, carrying out rational construction, and orderly conducting technical improvements to the power grid assets are the foundation and guarantee for the safe, stable, and efficient operation of the power grid. Therefore, conducting research on the management of physical assets in the power grid and enhancing the level of asset operation and management in power grid enterprises have significant practical implications. This study applies the asset wall model and combines the average lifespan of physical assets to optimize the prediction and analysis method using the Weibull probability model. Through this approach, the long-term investment requirements for upgrading outdated equipment in the power grid can be scientifically evaluated, and the accuracy of investment prediction for technology upgrades can be effectively improved.
