Implementation of a Transmission Line Model with the PEEC Method for Lightning Surge Analysis

This paper proposes a simple transmission line model adopted with the partial element equivalent circuit (PEEC) method for lightning surge analysis. The proposed approach is employed for calculating tower surge responses and voltages across insulators of an actual transmission tower. The proposed approach increases the efficiency of the method in terms of computation time because of reducing a ...

Lightning Surge Analysis on Grounding Models of a Transmission Lines

Lightning has been one of the important problems for insulation design of power systems and it is still the main cause of outages of transmission and distribution lines. The lightning return-stroke current and the charge delivered by the stroke are the most important parameters to assess the severity of lightning strokes to power lines and apparatus. In order to calculate lightning surge analys...

Simulation of Lightning Surge Propagation in Transmission Lines Using the FDTD Method

power transmission lines. Numerical computation of solving the Telegraphist’s equations is determined and investigated its effectiveness. A source of lightning surge wave on power transmission lines is modeled by using Heidler’s surge model. The proposed method was tested against medium-voltage power transmission lines in comparison with the solution obtained by using Bewley lattice diagram. As...

On the transmission line model for lightning return stroke representation

[1] The widely used transmission-line (TL) model of lightning return stroke in a vertical channel is most rigorously represented by a vertical phased array of current sources that produce a spherical transverse electromagnetic (TEM) wave in the case of return-stroke speed v equal to the speed of light c. If the radius of the lightning channel were equal to zero, the equivalent representation co...
