Abstract(s)
Nesta dissertação é apresentada uma metodologia que tem como principal finalidade descrever e calcular a potência produzida de um conversor elétrico de ondas oceânicas, mais especificamente um dispositivo de galgamento (WD - Wave Dragon), em regime offshore e a sua colocação em território português - Leixões.
Numa fase inicial da dissertação serão descritos alguns conversores e as suas características, seguindo-se uma introdução teórica das ondas regulares e irregulares e, posteriormente será exposta e calculada a influência dos refletores na onda incidente, energia e caudal transposto.
Por fim, será calculada a potência expectável para um certo estado de mar na zona de Leixões se fosse colocado o WD.
Este estudo permite avaliar a complexidade e imprevisibilidade das ondas, analisar o comportamento do conversor consoante as suas características de construção, dimensão e requisitos.
This dissertation presents a methodology that aims to describe and calculate the power produced by an oceanic waves electrical converter, more specifically an overtopping device (WD – Wave Dragon) in an offshore regime and its placement in portuguese territory in the area of Leixões. On an initial phase of the work some converters and their features will be described followed by a theoretical introduction to regular and irregular waves. Then the influence of reflectors on the incidental wave, energy and overtop flow will be exposed and calculated. In the final phase will be calculated the expected power for a certain state of the sea around Leixões if the WD was used there. This work allowed to evaluate the complexity and unpredictability of the waves, analyze the performance of the converter according to its building features, dimension and requirements of the technology used.
