Abstract: This article introduces the application scheme of modular prefabricated substations in the Shage Desert area, mainly including main transformer module, GIS module, medium voltage distribution module, reactive power compensation module, secondary equipment module, basic structure module, etc. Each module scheme is optimized and designed according to the climate characteristics of the Shage Desert area, adopting standardized design, factory processing, and modular construction mode, with the goal of "saving time, land, heart, and money". It has strong adaptability and promotion value, and can also be well applied in other regions.
