Abstract
A technique for correcting measurement error in data produced by a nacelle-based anemometer and for determining free stream wind speed for a wind turbine involves ascertaining parameters related to the wind turbine and the operation thereof, and using the parameters and data from the nacelle based anemometer as inputs to an algorithm to provide for determination of corrected wind speed data.
Claims13
A method for determining corrected wind speed data for a wind driven turbine comprising a nacelle based anemometer, the method comprising:
- measuring wind speed with the anemometer to produce uncorrected wind speed data;
- receiving the uncorrected wind speed data in a processing unit;
- obtaining values for parameters for the turbine operation by at least one of measuring the parameter values and selecting predetermined parameter values;
- and,
- processing the uncorrected wind speed data and the values with the processing unit to determine the corrected wind speed data.
A system for producing corrected wind speed data for a wind turbine comprising a nacelle based anemometer, the system comprising:
- at least one sensor for measuring at least one operational parameter of the wind turbine and producing at least one dynamic value, wherein the at least one sensor comprises the nacelle based anemometer for producing uncorrected wind speed data;
- a processing unit coupled to the at least one sensor, the processing unit comprising memory for storage of an algorithm and storage of at least one predetermined static value, wherein the processing unit receives the uncorrected wind speed data and the at least one dynamic value and produces the corrected wind speed data using the uncorrected wind speed data and at least one of the static value and the dynamic value as inputs to the algorithm.
A computer program product stored on machine readable media, the product comprising instructions for determining corrected wind speed data for a wind driven turbine comprising a nacelle based anemometer, by measuring wind speed with the anemometer to produce uncorrected wind speed data;
- receiving the uncorrected wind speed data in a processing unit;
- obtaining values for parameters for the turbine operation by at least one of measuring the parameter values and selecting predetermined parameter values;
- and, processing the uncorrected wind speed data and the values with the processing unit to determine the corrected wind speed data.
A system for producing corrected wind speed data for a wind turbine comprising a nacelle based means for measuring wind speed, the system comprising:
- means for obtaining at least one operational condition of the wind turbine, the at least one operational condition comprising at least uncorrected wind speed data;
- and,
- processing means coupled to the obtaining means, the processing means comprising means for receiving at least one value for the at least one operational condition and further comprising means for producing corrected wind speed data using the at least one value.
