Usage of the Computational Intelligence to Create Algorithms for Determination the Number of Lightning Strokes to Objects of Critical Infrastructure

Abstract

Usage of the computational intelligence to create algorithms of the statistical model that describes the electro physical processes at the last stage of the the lightning leader channel movement to the ground, taking into account the possibility of propagation of a counter spark from ground objects has been proposed. This model is based on experimental data on the speed of the lightning leader channel, the electric field strengths necessary for the development of leader channels of negative and positive polarity, etc. The correspondence of this model to the considered processes is confirmed by comparing the results of calculation the probabilities of places destruction by high-voltage discharge of the earth and objects located on it with known experimental data. An example of the model implementation for appreciation of the prognosticated lightning strikes to an object of the critical infrastructure, namely tanks for oil storage, has been presented.
