Research on a Method for Automatically Generating Single Line Maps in Distribution Network GIS

The scale of power grid equipment, the number of power customers and the complexity of grid structure in China are among the highest in the world. In addition, the rapid change of power grid and the frequent transformation of equipment make the automatic generation of single line diagram, especially the single line diagram of distribution network GIS, increasingly difficult. The traditional manual drawing method has the disadvantages of heavy workload, low efficiency and uncontrolled accuracy. At the same time, due to the influence of human drawing habits, the readability of the finished product is low, which cannot meet the requirements of the increasingly updated power grid for its own maintenance and management. In this paper, a specific algorithm is used to determine the flatness of the original drawing, realize orthogonal mapping, and flatten the complex electrical wiring information. Finally, the experimental results show that the algorithm can realize the decoupling of complex wiring diagram, and significantly improve the mapping efficiency and accuracy.
