Under the background of power systems driven by the pressure from carbon emission reduction, the new power system has been developed rapidly. As a guarantee of electricity use, the distribution room is becoming increasingly intelligent. This paper analyzes the digital management system of intelligent distribution room. The composition and functions of digital management system of intelligent distribution room is firstly illustrated. The digital management system of intelligent distribution room based on the eIoT (electric Internet of Things) is then proposed. The working state of the digital management system of intelligent distribution room, together with its component modules in architecture, and its detailed application in implementation is illustrated. From the actual operation effect of the digital management system of intelligent distribution room, based on the eIoT, is helpful to save the labor cost and prevent accidents to some extent.
