Transmission and distribution grids and Unified Modeling Systems

The present invention provides a method and system for transmission and distribution grid Unified Modeling, CIM-based distribution network model was constructed based on the actual situation of the grid system, and the introduction of the feeder vessel, constructed hierarchical relationship between the station and the different types of plants with sites outside of the apparatus to complete the construction of transmission and distribution network model, after re-transmission and distribution network according to the obtained data and the transmission and distribution network unified business model, unified control of the grid. The whole process is true, accurate construction of transmission and distribution grids unified model, unified service data acquisition transmission and distribution network, to achieve a unified power grid business precise control to ensure the safety of the grid system, efficient operation.
