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. Evaluation of field tests of different ice measurement methods for wind power : focusing on their usability for wind farm site assessment and finding production losses

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

   Author : Helena Wickman; [2013]
   Keywords : wind power; cold climate; ice detector; production loss; site assessment; vindkraft; kallt klimat; isdetektor; produktionsförlust;

   Abstract : The favorable wind recourses in many cold climate regions make them interesting for development of wind farms. However, with the cold climate come drawbacks due to icing. Production losses, fatigue loadings, ice throws and increased noise are some of the more severe issues that have to be addressed. READ MORE
