dc.description.abstractAbstract. This Phd Thesis was focused on the lightning induced transients modeling on long and complex networks and the induced voltage measurements on energized distribution networks. Here is described and compared two methodologies for the induced transient calculation which are implemented in three different software linked to a transient analysis program (LIOV-EMTP, LIV-ATP and YALUK-ATP). The YALUK-ATP is a software developed in this PhD thesis which improves the link with the transient program; this new proposal allows make link without including an additional delay on the traveling waves. The developed software (YALUK-ATP) and the LIOV-EMTP showed to have the best features calculating lightning-induced voltage on complex networks; these software are used for the analysis of the network topology on lightning-induced voltages calculation for a different stroke location and ground conductivity. Moreover, as an engineering application, it was developed a new software which uses the advantages of YALUKATP and the genetic algorithms technique to locate appropriately surge arresters on a complex distribution network. As a new contribution, it was built a new lightning-induced voltage measurement system on an energized distribution network which uses fiber optics and solar energy technology in order to reduce the electromagnetic interference. This distribution network is located 100m far away from the Colombian direct natural lightning measurement station where the induced voltage signals are gathered and registered. Nowadays, in Colombia, it has been measured more than 200 induced voltages on two measurement systems which were analyzed on this Phd Thesis. Several measurements have been correlated with the Colombian Lightning Location System and compared with calculations made with the induced voltage software.
dc.description.abstractEsta tesis de doctorado está enfocada en el modelamiento de tensiones inducidas en sistemas de distribución largos y complejos y la medición en redes energizadas. En este documento se describen y comparan dos metodologías para el cálculo de tensiones inducidas, las cuales están implementadas en 3 programas computacionales vinculados con un programa para análisis transitorio (LIOV-EMTP, LIV-ATP, YALUK-ATP). El YALUK-ATP es un programa computacional desarrollado durante esta tesis doctoral, el cual es vinculado con el ATP por medio de una nueva metodología propuesta en esta tesis. Los programas YALUK ATP y LIOV-EMTP mostraron ser adecuados para el análisis de tensiones inducidas en sistemas complejos. Adicionalmente, fue realizado un programa computacional como aplicación en ingeniería el cual utiliza las ventajas del uso del YALUK-ATP, para el cálculo de tensiones inducidas, y la técnica de algoritmos genéticos, para optimización. Este nuevo programa estima la localización más adecuada de descargadores de sobretensión en sistemas de distribución complejos. Como aporte adicional a la investigación mundial fue construido un nuevo sistema de medición de tensiones inducidas en una red energizada, usando técnicas como fibra óptica y tecnología de energía solar para disminuir los efectos de interferencia. La red está localizada a 100m de distancia de la estación de medición directa de rayos colombiana y en ella son registradas todas las mediciones. En la actualidad, en Colombia, se han realizado más de 200 mediciones de tensiones inducidas que fueron descritas y analizadas en esta tesis doctoral. Algunas de las mediciones han sido correlacionadas con el Sistema de Localización de Rayos Colombiano obteniendo los datos de localización y amplitud de los rayos generados. En este documento se describió los resultados encontrados al realizar esta comparación.
