Full textNos sociétés sont fortement dépendantes de l'électricité, et il ne fait pas de doute que la fonctionnalité des lignes de transport est déterminante pour assurer la fiabilité des réseaux électriques modernes. En effet, la continuité de l'approvisionnement en électricité reste la préoccupation majeure de toutes les compagnies d'électricité, et cette continuité du service peut être compromise par une multitude d'incidents ou d'accidents sur l'ensemble du réseau. Parmi toutes les sources possibles de charges dynamiques sollicitant les lignes de transport, celles provenant des effets du vent sur les pylônes et les conducteurs restent les plus fréquentes. Les conducteurs de lignes sont particulièrement vulnérables aux effets du vent car les portées sont longues et flexibles (comparé aux pylônes) et leur présence physique dans le réseau en font des structures exposées à toutes les intempéries qui peuvent survenir sur le territoire couvert. Cette vulnérabilité est encore plus grande dans les climats nordiques où les effets combinés du givrage atmosphérique et du vent créent des scénarios de charges de conception parmi les plus critiques et donc susceptibles de contrôler la conception finale des lignes. Il nous apparaît donc essentiel de comprendre la dynamique des fluides des effets du vent pour prédire avec réalisme et un degré de précision raisonnable la pression du vent exercée sur les conducteurs. Une meilleure évaluation des charges dues au vent permettrait par le fait même des prédictions plus réalistes de la réponse des lignes aux charges de vent, non seulement en terme de déplacements et dégagements électriques mais aussi en terme des charges nettes transférées aux pylônes par les conducteurs. La nature aléatoire des effets du vent sur les conducteurs a déjà fait l'objet de nombreuses études scientifiques et les méthodes d'analyse stochastique modernes permettent de cerner la question : les méthodes de conception simplifiées qui sont suggérées dans les normes et guides tiennent compte de ces effets en utilisant un coefficient de portée global qui ajuste à la baisse les efforts calculés au pylône sous des charges supposées synchrones et uniformes le long des conducteurs. Cette recherche ne concerne pas cet aspect de la question. Nous croyons que des gains de précision appréciables dans la prédiction des charges de vent sur les lignes sont possibles par une meilleure modélisation de la physique des effets du vent sur les conducteurs, dans les conditions givrées ou non, en utilisant les techniques d'analyse qui tiennent compte des interactions dynamiques fluide-structure. Ces interactions sont ignorées dans les méthodes d'analyse conventionnelles qui consistent simplement à calculer une pression statique proportionnelle à la vitesse carrée du fluide selon l'équation classique de Bernoulli. Bien sûr, les concepteurs ne négligent pas la considération des vibrations éoliennes ou du galop des conducteurs, mais ces phénomènes sont traités séparément et n'influencent pas le calcul des charges sur les pylônes. Dans cette recherche, nous nous intéressons aux conditions de vent de rafale avec grande turbulence qui caractérisent les tempêtes de vent. Ces vents forts et turbulents créent de grands déplacements des conducteurs qui modifient les conditions d'écoulement d'air. Une évaluation plus précise de ces conditions est possible par analyse computationnelle des interactions vent-conducteur.Les bases théoriques de la physique des phénomènes en présence sont connues mais aucun cadre d'application numérique n'a été proposé jusqu'à maintenant, en partie à cause des coûts numériques élevés mais aussi dû au manque de données expérimentales pouvant valider ces modèles computationnels.Nous avons développé un tel cadre d'analyse computationnelle dans cette recherche et l'avons illustré dans un cycle complet, du calcul des charges au calcul de la réponse d'une section de ligne, avec plusieurs exemples pratiques à chacune des étapes de développement

Full textThis study resulted from a perception held by the author that more attention is afforded to complying with the procedural elements of Environmental Impact Assessment (EIA) in South Africa, than to ensuring the validity of its technical content. The routing of high voltage overhead transmission lines provides a relevant field of study in which to address this perception. An initial literature review to contextualise the perceived problem showed that the questionable validity of the technical content of EIA was one of six shortcomings identified. To address the problem, an inductive approach was adopted to focus on the interpretation and prediction activities of EIA and two propositions, stated as research questions for discussion, were developed. These referred to the theoretical question of whether methods are specified for high voltage overhead transmission line EIAs, and to the practical question of whether the environmental impacts that are known to result from transmission line projects are effectively addressed in such EIAs in South Africa. Investigating these questions provides insights into whether the technical content of transmission line EIA is sufficiently rigorous in South Africa. The method of study takes the form of a sequentially more focused examination of the literature on EIA, from the strategic level, to the sectoral level and culminating at the project level. EIA methods specified for linear developments were identified at the sectoral level, while at the project level the known environmental impacts that result from high voltage overhead transmission lines were determined. A theoretical background was compiled in this way, which allowed for comparison with the practice as determined from benchmark and case study Environmental Impact Reports (EIRs).

Resumo: O objetivo deste trabalho é calcular os parâmetros longitudinais e transversais de linhas de transmissão trifásica a partir das correntes e tensões nas fases das mesmas. Serão utilizadas equações desenvolvidas no domínio modal considerando as obtenções de correntes e tensões em um terminal da linha enquanto o outro terminal permanece em aberto ou em curto-circuito. Inicialmente é apresentada a teoria básica de linhas de transmissão partindo do pressuposto de que tais linhas são melhores representadas através do modelo de parâmetros distribuídos. Assim através da análise de circuitos elétricos e das leis de Kirchhoff são encontradas as equações diferenciais de segunda ordem de tensão e corrente que caracterizam a linha de transmissão. Em seguida é apresentada a metodologia para cálculo dos parâmetros da linha que utiliza a idéia de impedância equivalente de circuito aberto e curto-circuito quando um dos terminais está em aberto e em curto-circuito respectivamente. Utilizando o Toolbox SimPowerSystem do MatLab são simuladas a obtenção das correntes em linhas de transmissão trifásica de 330 kV, 440 kV e 500 kV, todas com comprimento igual a 500 km. De posse de tais correntes são calculados os parâmetros das linhas de transmissão e comparados com seus valores reais, mostrando a viabilidade da metodologia empregada e que o erro obtido com tal metodologia é menor do que o erro entre os parâmetros reais das linhas após construção e seus parâmetros de projeto existente nos bancos de dados das empresas.
Abstract: The objective of this work is to calculate the longitudinal and transversal transmission line parameters using phase currents and voltages. Developed equations are used, in the modal domain, considering current and voltages found between a line terminal and an open line terminal, and a short-circuit terminal. . Initially, the basic transmission line theory is presented assuming that these lines are best represented by distributed parameters model. Therefore, through the analysis of electric circuits and Kirchhoff's laws , second order differential equations for voltage and current are found, which characterizes the line transmission. Next it is shown the method to calculate the line parameters, which uses the concept of open circuit and short-circuit equivalent impedance when one of the terminals is open or in short-circuited respectively. Using the Toolbox of MatLab, SimPowerSystem, estimated currents are simulated in a three-phase transmission line of 330 kV, 440 kV and 500 kV, all with the length of 500 km. The found values are used to calculate parameters of lines transmission and to compared them with their real values, showing that the calculation is possible and that the error obtained with this method is smaller than an error between the real line parameters after construction and those of existing project in the data base of companies.

The purpose of this study is to examine the effects of EMP coupling on overhead transmission lines. First, a theoretical model of multiconductor transmission line is derived and used to obtain the transfer function of an EMP coupling to the transmission line. On the basis of this function, the coupling effects of two-conductor and multiconductor transmission lines are analyzed by varying the incident angle, the termination impedance and the associated dimension. The proximity effect is also discussed. Finally, the lossy ground effect is investigated by varying the lossy parameters, and the wire to ground distance.

ABSTRACT Lightning strike is a natural phenomenon. The insulators of transmission systems will be flashover and causing the breakers trip if the lightning surge invades. The outages of power system are then resulted. The parameters that affect lightning transients of power transmission system include tower characteristics、ground resistance and lightning surge characteristics (front time and peak values). In this thesis, the ATP/EMTP package is used to simulate the back flashover transient voltage of 161kV overhead transmission system. tower caused by lightning strikes. The multi-story model of tower is adopted. The different ground resistance and lightning characteristics are considered in the simulations. The performances of line arresters installed are also observed. The data obtained can be used as references for lightning protection design.
