Omdimensionering av instrument för mätning av vindhastighet

Sammanfattning: The ever-growing demand for renewable energy leads to an increased need for innovation in the green energy sector. One of the available alternatives, wind power, have seen a global increase in usage with few signs of slowing down. To increase the efficiency of individual turbines, correct placement is crucial. One technology that uses sound to find optimal locations for wind turbines is Sonic Detection and Ranging, SODAR. AQ system manufacture and deliver SODAR-systems internationally. The size of the system created by AQs limit the locations which the system can measure wind. Occasionally this forces measurement to be made away from the location in question which potentially reduce the efficiency of the future wind turbine. This study aims to create a concept for a smaller version of the SODAR-system manufactured by AQs. A smaller system would allow wind measurement in more remote, hard to reach locations which in turn would increase precision of the measurements and potentially efficiency of wind turbines.   Tools from Ulrich & Eppingers product development process was used to generate, screen, and evaluate concepts throughout the study. By changing the geometry and positioning of individual components in the system the height was reduced by 49,7% and width by 32,8%. An even smaller concept could be presented if more focus was put on the base of the product. Many factors that could impact the function of the product have been ignored in this study. Based on the specifications put up for this project the concept could theoretically perform as the original AQ510. Considering that relevant factors have been ignored, the function of the concept cannot be guaranteed. The tools and methods used in the product development process facilitated the development and made it possible to present a concept within the time frame. The conclusion is that, based on the specifications presented, the concept reached the goals put up for the project but to be able to guarantee the performance of the concept, measurements and tests are needed.
