  1. 1. Modelling of ice throws from wind turbines

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

    Author : Joakim Renström; [2015]
    Keywords : Ice throw; icing; wind turbines; balistic model; Iskast; nedisning; vindkraftverk; ballistisk modell;

    Abstract : As the wind energy sector expands into areas with colder climate, the problem with ice throw will increase. Due to a rotor diameter of more than 120 meters for a typical modern turbine with an effect of 3.3 MW, the separated ice fragment will get a high initial velocity, and therefore, they will also be thrown a long distance.

  3. 2. Investigating the influence of farm layout on the energy production of simple wind park configurations

    University essay from KTH/Kraft- och värmeteknologi

    Author : Sercan Uysal; [2014]
    Keywords : renewable energy; wind energy; wind turbines; wake effect; wake loss; wind farm; wake models; windfarmer; layout optimization;

    Abstract : The interaction between wind turbines in simple wind farm layouts is investigated with the purpose of observing the influence of wake loss phenomenon on the energy production of downwind turbines. Following an intensive exploration stage about wind farm aerodynamics and wake modeling subjects, several tests cases are designed to represent various wind farm configurations, consisting of different number of wind turbines.

  4. 3. Ways to a further prevention of wind turbine noise disturbance : the extent to which the current sound assessment methods are satisfactory in noise estimation and possible improvements

    University essay from Institutionen för geovetenskaper

    Author : Mark Veenstra; [2013]
    Keywords : ;

    Abstract : This text reviews the topic on how improved understanding and assessment of noise from wind turbines can and should mitigate noise disturbance for neighbouring inhabitants. Experienced noise disturbance can lead to all kinds of problems for inhabitants, but also for wind power development in general: public attitude can turn negative, there can be claims, law suits and a reluctance of local authorities to welcome further wind power development.

  5. 4. Effects of a Forest Clearing: Experimentaland Numerical Assessment

    University essay from KTH/Mekanik

    Author : Tetsuya Nakamura; [2013]
    Keywords : ;

    Abstract : There is a renewed interest in the wind estimate over and around forest areas dueto the increasing demand of wind-energy resources. Many researches have been donewith simplied forest models. READ MORE

  6. 5. Wind Speed Prediction Models and Their Use in Wind Turbine Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Paolo Mattachini; [2013]
    Keywords : Technology and Engineering;

    Abstract : Wind energy production is a section that became bigger and bigger thanks to the interests in finding new ways to produce energy that do not involve fossil fuels because of environment concerns, because of their costs and because of their limited amount. Even though wind energy was exploited also in the past, for example in wind mills, it is with wind turbines that all the problems affecting these systems started to be taken into account and to be studied deeply.
