Abstract:
The majority of the different parts of our work in this thesis in resume: A contribution to the
study and analysis of lightning and its effects of electromagnetic coupling with the electrical
networks HTB. Lightning is a very severe electrical stress on HTB electrical networks, the
physical and electrical description of this phenomenon is an advantage and an important input
for the rest of our work. The modified versions of the MTL model used in this work, being the
most reasonable compromise between mathematical simplicity and precision. A mathematical
analysis of electromagnetic coupling equations and based on recent work by authors, we
concluded that the Agrawal model is the most suitable for this type of calculation. We develop
the essential of our contribution. Using Agrawal's formalism, we expose our concept for the
electromagnetic interaction of lightning with an overhead power line HTB. We also propose an
extension of this formalism to the analysis of an HTB line network. We have abordating, the
quantification by calculation of the electromagnetic effect of the lightning with an electric
network HTB. This we have established a program Matlab simulation to facilitate our calculation
task.
