Abstract: Abstract:This paper discusses the technical characteristics of the prefabricated smart substations and distributed energy systems, with distributed energy projects as examples, following prefabricated substation’s design guidance——“compact + digitalized”, and in accordance with electric and construction designing requirements of these projects, electronic equipment are categorized into different modules whose respective functions，equipment type selection and arrangement methods are further introduced in detail. In this way, distributed energy station works well with each module functioning distinctly, requiring less maintenance and simple operation procedures, which has the project quality，project period and project cost effectively under control.
