Propuesta Metodológica para la Coordinación de Aislamiento en Redes Eléctricas de extra alto voltaje usando modelación electromagnética y distribución probabilística de sobrevoltajes.

Abstract

The following paper exposes a methodology for coordination of insulation in the highest voltage electric systems, this guide obtains over voltage through the analysis of electromagnetic modeling and probabilistic distribution, for which the computational tool EMTP is used. The methodology is presented accompanied by a graphical interface, in which the data required from the electric system are entered in the order that has been established in the proposed methodology. This study is conceptualized in seven chapters, first chapter has the introduction and importance of the study, together with the objectives of this work. The second chapter has the most significant aspects of: insulation coordination, over voltages, and the parameters established by the IEC 60071 standard. The third chapter illustrates the electromagnetic representation by the most relevant components of an electric system. Next, fourth chapter, explains about the probabilistic distribution. The fifth chapter exposes the proposed methodology and the developed interface. Continue, sixth chapter has an application system by be used as example. And finally, the seventh chapter presents the conclusions and recommendations concerning the present study.
