Automatic Generation of Substation Power Network Diagram based on the Existing Diagrams Feature Library

This paper proposes a method for automatic generation of the power network diagram of plants and substations for grid dispatching system. Establish a local graphic feature library in layers, extract the feature quantity of the existing plant diagrams based on graph-model-data-database integration. Match the features of new diagram and the existing diagrams layer by layer. Then Generate the new diagram automatically with combination, replacement, addition and subtraction of the existing diagrams containing the characteristics of the target diagram.
