Abstract
Vegetation management is a key activity for E-REDES, the Portuguese main DSO, in order to ensure the reliability and safety of the electric grid and to preserve the environment on its surroundings. In particular, the low voltage power (LV) grid poses a significant challenge, due to its extension, characteristics and lack of adequate technologies for inspection. Nowadays, the search for vegetation anomalies at low voltage level is done via visual inspection that are part of the systematic rounds, done periodically by vehicle to the grid. To face the vegetation management difficulties and to leverage on those car rounds, E-Redes developed and tested, in partnership with everis, a proof of concept for the application of computer vision technology to identify vegetation issues in the LV grid through the analysis of video footage of the grid recorded by a moving vehicle. The paper will address the strategy and methodology for implementing this solution, the technical approach, the results obtained during the test phase and the insights gathered from those tests. With this work, it was possible to recognize the challenges of using this type of technology in the low voltage grid context and to design future improvements to this type of solutions.
