1. 1. An in-depth comparative study of direct drive versus gearbox wind turbines

   University essay from KTH/Energiteknik

   Author : Alexandre Maxìme Andre Marx; [2018]
   Keywords : ;

   Abstract : The wind turbine industry is constantly growing and new concepts are flourishing to improve the performance of the turbine drive-train. Typically in conventional large-scale wind power generators, a gearbox is used between the turbine rotor and the electrical generator to increase the rotational speed from around 100 rpm to around 1200 rpm.

3. 2. Investigating CVT as a Transmission System Option for Wind Turbines

   University essay from KTH/Energiteknik; KTH/Kraft- och värmeteknologi

   Author : Deniz Alkan; [2013]
   Keywords : Continuously variable transmission CVT ; wind turbine drive train; blade element momentum BEM ; frequency control of wind turbines; power electronics;

   Abstract : In this study, an innovative solution is examined for transmission problems and frequency control for wind Turbines. Power electronics and the gear boxes are the parts which are responsible of a significant amount of failures and they are increasing the operation and maintenance cost of wind turbines. READ MORE

4. 3. Meta Modeling of Transmission Error for Spur, Helical and Planetary Gears for Wind Turbine Application

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Muhammad Irfan; [2013]
   Keywords : Transmission error; Wind turbine; Meta-models; Abaqus 6.12-1; Spur gear; Helical gear; Planetary gear; Regression analysis.;

   Abstract : Detailed analysis of drive train dynamics requires accounting for the transmission error that arises in gears. However, the direct computation of the transmission error requires a 3-dimensional contact analysis with correct gear geometry, which is impractically computationally intense. READ MORE
