Correction method for wind speed measurement at wind turbine nacelle

摘要

A technique for correcting measurement error in data produced by a nacelle-based anemometer (21) and for determining free stream wind speed for a wind turbine (10) involves ascertaining parameters related to the wind turbine (10) and the operation thereof, and using the parameters (72) and data from the nacelle based anemometer (21) as inputs to an algorithm to provide for determination of corrected wind speed data (91).
