Abstract Taking a project as an example，a technical and economic comparison between 35 / 0 .4 kV and 35 / 10 / 0.4 kV power transformation and distribution schemes for ultra-large buildings substations are made on several aspects， such as the major equipment investment，floor area，power consumption and so on，the project has finally adopted a 35 / 10 / 0.4 kV two -stage power transformation scheme.
