Analysis of Overhead Distribution Lines Performance under Lightning Surges

Scientific Study from the year 2009 in the subject Engineering - Power Engineering, , course: Power Systems Electrical Engineering, language: English, abstract: The medium voltage system performance analysis of front lightning discharges is very dependent on its modeling. As the model approaches the reality, the more it becomes extremely complex and time expensive. As a result, it generally leads to the adoption of some sort of simplifications and approximations. The present work aims at the study of a large variety of effects of the lightning discharges, its impacts and preponderant factors for analysis in different real systems, as far as searching for a balance between the model's approximation and the resultant errors. With this in mind, it uses models that are more precise, stochastic process simulations, electromagnetic transient simulations, real information from the networks and statistical analyses. Therefore, it is possible to establish the main intervention points for the improvement of the medium voltage overhead distribution system performance front lightning discharges.
