Lightning induced voltages on overhead power lines are calculated in this paper by using different return stroke engineering models for the evaluation of electromagnetic fields.

Finite difference time domain (FDTD) technique with the second-order scheme is used for numerical solving of the governing equations.

Abstract
Lightning induced voltages on overhead power lines are calculated in this paper by using different return stroke engineering models for the evaluation of electromagnetic fields. Agrawal formulation is used for field-to-line coupling equations and Cooray-Rubinstein correction is applied in order to include the impact of the finitely conducting ground. Finite difference time domain (FDTD) technique with the second-order scheme is used for numerical solving of the governing equations. PSCAD-EMTDC computer code is applied for the computation of results for different distribution line terminations, different finite ground parameters and different stroke locations.File | Dimensione | Formato | |
