Abstract
Vegetation management of power grids is essential for reliable distribution of services, prevention of forest fires and disruption of electricity due to tree fall. In this paper, we introduce a vegetation analysis system that utilizes information from GIS data, aerial and satellite imagery to estimate vegetation profile within a buffer zone. This vegetation profile is further combined with operational parameters of the grid to develop a survival model which predicts the outage risk of a power-line in an electrical grid. Using historical data, we show that the risk scores thus obtained are significantly better at developing trimming schedules for grid power-lines, compared to existing available methods.
