Abstract

The increment in the electricity use and the necessity or transferring large volumes of energy in an efficient and safe form, raises the necessity of looking for the faults frequency diminution, as well as the transmission and distribution power line optimization. For this purpose, the calculation of the required dielectric distances in the power lines design stage, can only be obtained through a better knowledge of the dielectric stresses resulting from the surges of internal origin (connection maneuvers) or external (atmospheric discharges) and from the temporary or permanent degradation, introduced on the insulating materials by the diverse environmental factors and meteorological parameters (contamination, humidity, temperature, rain, etc.). Of these, the contamination is the cause of a high percentage of faults and the present thesis work is related to the contingencies originated by this factor. In order to face the problem, in Mexico, it is being developed a research project in the matter of contamination denominated Contamination Effects on Insulations. As a part of this project, this thesis work analyzes some hypotheses about the dynamics of the accumulation of polluting agents on the insulators, considering the most important factors in the evolution of the contamination phenomenon; namely: the meteorological parameters, the  More>>

In order to face the problem, in Mexico, it is being developed a research project in the matter of contamination denominated Contamination Effects on Insulations. As a part of this project, this thesis work analyzes some hypotheses about the dynamics of the accumulation of polluting agents on the insulators, considering the most important factors in the evolution of the contamination phenomenon; namely: the meteorological parameters, the insulator morphology and the period of exposure to the environment. In its present state, the investigation in our country in this field, as well as the computer tools and data banks of the project, allow to obtain in this work saturation curves for the insulators under study. These curves, essentially give the maximum contamination levels as well as the accumulation velocity of polluting agents, time based. The usefulness of these curves is in its application in the insulation coordination calculation to determine the fault distance required and the insulator appropriate configuration in regions in severe contamination regions. Also, they are useful for the development of models that allow establishing the maintenance periods that, with a minimum cost, diminish in a substantial way the fault index of the national electrical system. [Spanish] El incremento en el uso de la electricidad y la necesidad de transferir grandes volumenes de energia en forma eficiente y segura, plantea la necesidad de buscar la disminucion de la frecuencia de fallas, asi como la optimacion de las lineas de transmision y distribucion. Para esto, el calculo de las distancias dielectricas requeridas en la etapa de diseno de lineas, solo podra lograrse a traves de un mejor conocimiento de los esfuerzos dielectricos producto de las sobretensiones de origen interno (maniobras de conexion) o externo (descargas atmosfericas) y la degradacion temporal o permanente, que introducen sobre los materiales aislantes los diversos factores ambientales y parametros meteorologicos (contaminacion humedad, temperatura, lluvia, etc.). De estos, la contaminacion es la causa de un alto porcentaje de fallas y el presente trabajo de tesis se relaciona con las contingencias originadas por este factor. Para hacer frente al problema, en Mexico se desarrolla un proyecto de investigacion en materia de contaminacion denominado Efectos de la Contaminacion en Aislamientos. Como parte de este proyecto, este trabajo de tesis analiza algunas hipotesis acerca de la dinamica de acumulacion de contaminantes en los aisladores, considerando los factores mas importantes en la evolucion del fenomeno de la contaminacion; a saber, los parametros meteorologicos, la morfologia del aislador y el periodo de exposicion al medio ambiente. En su estado actual, la investigacion en este campo en nuestro pais, asi como las herramientas de computo y bancos de informacion del proyecto, permiten obtener en este trabajo curvas de saturacion para los aisladores bajo estudio. Estas curvas, esencialmente dan los niveles maximos de contaminacion asi como la rapidez de acumulacion de contaminantes en funcion del tiempo. La utilidad de estas curvas esta en su aplicacion en los calculos de coordinacion de aislamiento para determinar la distancia de fuga requerida y la configuracion apropiada del aislador en regiones en las que la contaminacion es severa. Tambien, son utiles para el desarrollo de modelos que permiten establecer los periodos de mantenimiento que, con un costo minimo, disminuyan de manera importante el indice de fallas del sistema electrico nacional.}
