Abstract
El principal objetivo de este trabajo de título consiste en la determinación de los sitios, a lo largo de la costa chilena entre la región de Valparaíso y de la Araucanía, que se presentan como los más adecuados para la extracción de energía a partir del oleaje, utilizando como modelo numérico de transferencia de oleaje de tercera generación SWAN. Adicionalmente, esta información es utilizada en la toma de decisiones del proyecto CORFO-INNOVA 09CN14-5718.Con el fin de contextualizar la problemática, en primer lugar se realizará una revisión del estado del arte, tanto a nivel internacional como nacional. De esta manera se busca determinar los avances y las nuevas problemáticas que surgen.Para llevar a cabo este estudio, se obtendrá, desde el NOAA, una base de datos correspondiente a 13 años, desde Enero de 1997 hasta Marzo del 2010, para 8 puntos en el área investigada. De esta base, se recopilaran los parámetros de resumen para dos estados de mar por día, con el fin de propagarlos hacia la costa utilizando el modelo numérico. A diferencia de estudios anteriores, se utilizaran grillas anidadas en la cercanía a la costa, como una manera de mejorar la modelación de los procesos físicos relevantes en aguas someras.A partir de los resultados obtenidos se extraerá la información para una profundidad de 50 m, con la cual se calculará el flujo medio de energía en toda la zona costera. Luego, se realizará una primera selección con las ubicaciones más energéticas, las cuales, según lo esperado, deberían corresponder a los sitios que presentan una configuración geográfica determinada, conocida como ‘punta’. De no ser así, estos sitios se incluirán de igual manera, con el fin de analizar su comportamiento. Utilizando un análisis multicriterio sobre los sitios seleccionados, el cual considera parámetros tales como la cantidad de energía disponible, la pendiente del fondo marino, así como su ubicación con respecto a puertos y al Sistema Interconectado Central, se elaborará un ranking de las ubicaciones más adecuadas para la extracción del recurso energético. Finalmente, se realizará un análisis estadístico del recurso en cada uno de los sitios seleccionados, así como un análisis de la potencia de salida asociada a distintos dispositivos generadores de energía.Del estudio a realizar, se espera que la zona investigada presente ubicaciones con un alto potencial energético, ideal para la extracción del recurso. En base a estudios anteriores y conocimientos de la zona, se espera una media cercana a los 30 kW/m y una baja variabilidad, tanto estacional como interanual.
The main objective of this title is the determination of sites, along the Chilean coast between the regions of Valparaiso and the Araucanía, presented as the most suitable for the extraction of energy from waves, using SWAN as a transfer numerical wave model, wich is a third-generation phase-averaged wave model. Additionally, this information is used in making project decisions for CORFO-INNOVA 09CN14-5718. To contextualize the problem, we will first conduct a review of the state of art, both internationally and domestically. This will seek to determine the progress and new problems that arise. To carry out this study, we will obtain from the NOAA a database for 13 years, from January 1997 until March 2010, of 8 points in the investigated area. From this database, the summary parameters will be collected for two states of the sea per day, in order to propagate them to the coast using the numerical model. Unlike previous studies, nested grids were used in close proximity to the coast, as a way to improve the modeling of relevant physical processes in shallow waters. From the results we will extract the information for a depth of 50 m, with which we will calculate the average power flow across the coastal zone. Then, we will make an initial selection of the most energetic sites, which, as expected, should correspond to sites that have a particular geographical setting, known as 'punta'. Otherwise, these sites will be included anyway, in order to analyze their behavior. Using a multicriteria analysis on the selected sites, which considers parameters such as the amount of energy available, the slope of the seabed and its location relative to ports and the Central Interconnected System, we will produce a ranking of the most appropriate locations for the extraction of the energy resource. Finally, we will perform a statistical analysis of the resource in each of the selected sites, as well as an analysis of the output power associated with different power generating devices. From the study to be performed, it is expected that the investigation area presents locations with a high energy potential, ideal for the extraction of the resource. Based on previous studies and knowledge of the area, it’s expected an average around 30 kW/m and a low variability, both seasonal and year.
