  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. CFD Study of the Flow around a High-Speed Train
