  1. 1. Automatised detection of sources for power curve deviations of horizontal axis wind turbines

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Marius Walter; [2022]
    Nyckelord :Wind Power; Automation; Power Curve; SCADA; Predictive Maintenance;

    Sammanfattning : To face climate change and transform the electricity supply to an environmentally friendly generation, wind plays an important role. Due to a yearly increase in installed wind power turbines, in the European Union, the need for maintenance increases as well. LÄS MER

  3. 2. ADAPTED FISH FRIENDLY OPERATION OF SMALL-SCALE HYDROPOWER PLANTS : AN ECONOMIC ANALYSIS

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ana Gil Merino; [2022]
    Nyckelord :;

    Sammanfattning : The hydropower sector generates almost half of the electricity produced in Sweden annually. Although hydropower is a renewable energy that produces no emissions, there is an impact on the local scale of Swedish aquatic ecosystem causing the decline of some fish species due to its impact on rivers connectivity.

  4. 3. Investigation on Positioning Techniques for Indoor Office Scenario

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Yan Shu; Yujie Zhang; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This master thesis aims to investigate downlink positioning techniques and improve fifth-generation (5G) cellular positioning performance in the indoor office scenario. In the thesis work, we target in the indoor office scenario because it is a typical deployment scenario standardized in 3GPP release 16. LÄS MER

  5. 4. Performance Analysis of Operating Wind Farms

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Abdul Mouez Khatab; [2017]
    Nyckelord :Performance analysis; Operating wind farms; SCADA; Operational power curve; Potential energy; Threshold power curves;

    Sammanfattning : This work proposes a methodology to evaluate the performance of operating wind farms via the use of Supervisory Control and Data Acquisition System (SCADA) and modeled data. The potential annual energy is calculated per individual turbine considering underperforming/loss events to have their power output in accordance with a representative derived operational power curve.

  7. 5. A Measurement Platform for Characterization of Quantum Cascade Lasers

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Joakim Storck; [2016]
    Nyckelord :;

    Sammanfattning : A measurement platform has been built to characterize quantum cascade lasers regrown at KTH by measuring their spectral and electrical properties at room temperature. Since the current source used in this work had a compliance voltage which was too low to get above threshold, an adapter was made to put an external voltage source in series with it, raising the voltage over the laser.
