Abstract:
A method of operating a wind turbine generator having at least one wind turbine blade includes increasing a pitch angle of the at least one wind turbine blade as the at least one wind turbine blade rotates through a first range of blade azimuth values. Such increasing of the pitch angle reduces acoustic emissions generated by the wind turbine generator. The method also includes decreasing the pitch angle of the at least one wind turbine blade as the at least one wind turbine blade rotates through a second range of blade azimuth values. Such decreasing of the pitch angle increases electric power generated by the wind turbine generator.
