The paper deals with the evaluation of lightning threat to distribution network feeders based on high-resolution flash density maps. High-resolution flash density maps with a resolution of 100 x 100 m are calculated from lightning information collected by a lightning location system. Lightning information used in a process of map calculation includes error ellipse, which is part of localization result, and is used for estimation of the location accuracy of a particular lightning event. Phases of map calculation are described and commented. By implementation of advanced topological and spatial analysis of the distribution network, it is possible to evaluate lightning threat probability per feeder. Feeder’s exposure may be afterwards presented with a probability curve relative to it’s length or with a single value as result of the momentum calculation also described in the paper. Results obtained with this evaluation are a basis for distribution line lightning protection optimization. |
