Abstract
A method for processing telemetry data for estimating a wind speed. The method includes a hybridization by temporal combination, and/or by weighting, and/or by averaged projection.
Claims17
A method for processing telemetry data for estimating a wind speed, said method comprising hybridization by temporal combination comprising:
- a step (A) of vector reconstruction of at least two components of an average wind speed vector over a time interval (Ω), called partition time interval, starting from successive projections, over time, of an instantaneous wind speed vector;
- a step (B) of scalar reconstruction of at least one average wind speed value (Vhave) over a time interval (T), called reference time interval, starting from a number (T/Ω) of the at least two components of the average wind speed vector reconstructed in step A;
- 2Ω is less than or equal to T and T/Ω corresponds to the number of the at least two components of the average wind speed over the partition time interval Ω included in the reference time interval T.
A method for processing telemetry data for estimating a wind speed, said method comprising hybridization by weighting comprising:
- a step (C) of vector reconstruction of at least two components of an instantaneous wind speed vector starting from projections of the instantaneous wind speed vector;
- a step (D) of vector reconstruction over a time interval (T), called reference time interval, of at least two components of an average wind speed vector starting from a number N of the at least two components, comprised over the reference time interval T, of the instantaneous wind speed vector reconstructed in step C;
- a step (E) of scalar reconstruction of at least one instantaneous wind speed value starting from the at least two components of the average wind speed vector reconstructed in step C;
- a step (F) of determining at least one average wind speed value starting from the at least one instantaneous wind speed value reconstructed in step E;
- a step (G) of determining at least one average wind speed value over the reference time interval T starting from the at least two components of the average wind speed vector reconstructed in step D;
- and
- a step (H) of determining at least one average wind speed value (Vhave) over the time interval T by weighting of a sum of the at least one average wind speed value reconstructed in step F and of the at least one average wind speed value determined in step G.
