Abstract:
The present subject matter is directed to a system and method for operating a wind turbine. The method includes determining an actual operating time for one or more wind turbine components at multiple power levels; determining a corresponding wind condition for each of the operating times at each power level; estimating a loading condition acting on the one or more wind turbine components at the multiple power levels and the corresponding wind conditions; estimating an accumulated fatigue life consumption of the one or more wind turbine components based at least partially on the operating times and the estimated loading conditions; and, operating the wind turbine based on the accumulated fatigue life consumption.
Abstract:
A system for mitigating wake losses in a windfarm is disclosed. The system may include a first horizontal axis wind turbine configured to rotate in a first direction and a second horizontal axis wind turbine positioned adjacent to the first horizontal axis wind turbine. The second horizontal axis wind turbine configured to rotate in a second direction, wherein the first direction is opposite the second direction.

Abstract:
A method for operating a wind turbine having at least one blade includes determining an ambient air operating envelope and controlling a power output of the wind turbine at least partially based on the determined ambient air operating envelope. Determining an ambient air operating envelope includes measuring at least one of an ambient air temperature, an ambient air pressure, an ambient air humidity, and wind turbine power output. The method also includes comparing at least one of a measured ambient air temperature, a measured ambient air humidity and a measured ambient air pressure to predetermined ambient air temperature, pressure and humidity values. The method further includes referencing the predetermined ambient air temperature, pressure and humidity values to at least one operational parameter of the wind turbine. The method also includes determining if an existing wind turbine power output is within a range associated with the determined ambient air operating envelope.
Abstract:
A method for operating a wind turbine is described. The wind turbine includes a tower having a tower axis, and a nacelle being rotatable about the tower axis. The method includes providing a data set of one or more operational parameters of the wind turbine. The one or more operational parameters depend on the angular position of the nacelle with respect to the tower axis. The method further includes determining an angular position of the nacelle with respect to the tower axis; selecting one or more operational parameters from the data set of one or more operational parameters of the wind turbine depending on the determined angular position of the nacelle; and applying the one or more selected operational parameters to the wind turbine. Further, another method of operating a wind turbine and a wind turbine are described.
