  1. 16. COMPARATIVE ANALYSIS OF WIND ATLASES: WIND RESOURCE ASSESSMENT OF FORESTED SITES FOR WIND POWER DEVELOPMENT

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joel Thomas; [2021]
    Keywords : ;

    Abstract : Wind atlases are interactive databases used extensively for preliminary wind resource assessment aimed at optimal wind power development. The selection and processing of wind atlas data are important and will determine the quality of the subsequent WRA (Wind Resource Assessment) phases. READ MORE

  3. 17. Gearbox fault detection, based on Machine Learning of multiple sensors

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Armands Krumins; [2021]
    Keywords : condition monitoring; gear; machine learning; surface fatigue;

    Abstract : The increasing demand for higher efficiency and lower environmental impact of transmissions, used in automotive and wind energy industries has created a need for more advanced technical solutions to fulfil those requirements. Condition monitoring plays an important role in the transmission life cycle, saving resources and time. READ MORE

  4. 18. Greenhouse gas emissions from three large lakes during the autumn 2020

    University essay from Linköpings universitet/Institutionen för tema

    Author : Veronica Bohlin; Anja Anderö Nordqvist; [2021]
    Keywords : methane; carbon dioxide; dissolved inorganic carbon; pCO2; flux chambers; large lakes; methane budget; carbon budget; GHGs; freshwater; spatiotemporal; ebullition; diffusion; autumn; metan; koldioxid; upplöst oorganiskt kol; pCO2; kammarmetod; stora sjöar; metanbudget; koldioxidbudget; växthusgaser; sötvatten; spatiotemporal; ebullition; diffusion; höst;

    Abstract : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. READ MORE

  5. 19. Harmonic Emissions in Microgrids

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Lejla Alibegovic; Emelie Freiland Paulsson; [2021]
    Keywords : Harmonics; microgrid; local energy system; NEPLAN; Technology and Engineering;

    Abstract : “Affordable and clean energy” is EUs 7th Sustainable Development Goal and includes an increase of renewable energy generation in the global energy mix. A lot of the responsibility falls on the energy sector to transform and obtain solutions for a more sustainable future. READ MORE

  6. 20. Verification of the local similarity theory above forests

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Yasmin Hubmann; [2021]
    Keywords : Forest Meteorology; Boundary Layer Meteorology; Wind Energy; Local Similarity Theory; Monin–Obukhov Similarity Theory; Flux-Gradient Formulation; Richardson Number Formulation; Turbulence Statistic; Rotor Equivalent Wind Speed; Grenzschicht-Meteorologie; Forstmeteorologie; Windenergie; Lokale Ähnlichkeitstheorie; Monin–Obukhov’sche Ähnlichkeitstheorie; Fluss-Gradient-Ähnlichkeit; Gradient-Richardson-Zahl Beziehung; Turbulenzcharakteristiken; Rotor-äquivalente Windgeschwindigkeit; Skogsmeteorologi; Gränsskiktsmeteorologi; Vindenergi; Lokal Similaritetsteori; Monin–Obukhov Similaritetsteori; Flöd-Gradient Relation; Richardson Gradienttal Relation;

    Abstract : In this study, the local similarity theory functions were calculated with two different approaches and on the other hand the mean hub height wind speed was compared with the rotor equivalent wind speed. Both calculations are based on two independent data-sets from measurement campaigns Hornamossen and Ryningsnäs which were conducted in the south of Sweden between May 2015 and June 2017, and November 2010 and February 2012.
