Using Geospatial Data to Generate One-line Diagrams of Electrical Power Systems

One-line diagrams are widely used to represent the electrical power system current state and its probable performance in the case of studies and simulations. Hence, its adequate construction is of great importance to avoid inaccurate decisions of the network operators. In order to reduce the human errors and the huge effort in a manual generation technique (usually adopted nowadays), this work proposes a methodology to automatically build these diagrams. The method is based on the usage of the geospatial data related to the network buses and branches with a graph algorithm that permits the elimination of superpositions of buses. The approach was successfully tested with the Institute of Electrical and Electronics Engineers (IEEE) 30 buses standard system and with a portion of the Brazilian network.
