  • Wind turbine rotor blade design
    Patent number: 11821402
    Abstract: A method of designing a wind turbine rotor blade. The method includes selecting a gravity load safety factor associated with wind turbine rotor blade fatigue loading due to gravity, that is selected to be less than a defined wind load safety factor associated with wind turbine rotor blade fatigue loading that is not due to gravity. The method includes determining a gravity-corrected design load for wind turbine rotor blade deflection, that is determined based on the selected gravity load safety factor and the defined wind load safety factor. The method includes designing a gravity-corrected wind turbine rotor blade in accordance with the determined gravity-corrected design load.
    Type: Grant

  • Wind turbine
    Patent number: 8441138
    Abstract: For optimising annual energy production in a wind turbine, the invention provides a method by which operation of the turbine in accordance with different pre-specified modes depending on the wind direction towards the turbine is enabled. The modes may include pitch and/or power control strategies. The invention further provides a control system for a wind turbine adapted to operate in accordance with the method, and a wind turbine with such a control system.
