  1. 1. Major Component Replacement on Floating Wind Turbines

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

    Author : Kilian Galle; [2023]
    Keywords : ;

    Abstract : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. READ MORE

  3. 2. Wind Turbine Recovery Forecasting using Survival Analysis

    University essay from Lunds universitet/Matematisk statistik

    Author : Anton Palets; [2023]
    Keywords : Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Abstract : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  4. 3. Comparative Analysis of Energy-Based and Revenue-Based Availability Metrics of Wind Turbines

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : El Mehdi Ouchlou; [2022]
    Keywords : KPI; time-based availability; energy-based availability; revenue-based availability; wind turbine availability;

    Abstract : Different key performance indicators are used to assess various aspects of a wind turbine (performance, reliability, financial aspects…). Availability metrics mainly, time-based and energy-based availability are the main indicators used to monitor and evaluate turbine’s availability performance today. READ MORE

  5. 4. Short-term O&M Planning for Offshore Wind Energy

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Miguel de Matos e Sá; [2022]
    Keywords : Offshore wind energy; O M scheduling; optimization; wake effect; weather forecasts; risk analysis; Portugal; WindFloat Atlantic; Havsbaserad vindkraft; planering av drift och underhåll; optimering; wake effect; väderprognoser; riskanalys; Portugal; WindFloat Atlantic;

    Abstract : Significant breakthroughs are currently being achieved for Offshore Wind Energy (OWE), as offshore wind turbines are moving further away from the shore, benefitting from as vaster wind resource availability. On the other hand, the current trends of the OWE industry make new challenges arise. READ MORE

  6. 5. Combining energy harvesting sources for increased system availability and using an input switching algorithm to maximise battery lifetime

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Anton Hylander; [2022]
    Keywords : ;

    Abstract : Energy harvesting is commonly used for powering low power electronics, for example Low Power Wide Area Networks (LPWAN). Many energy sources are natural (e.g. solar or wind), thus the harvested power can depend on weather, time of day, and time of year. READ MORE
