SYSTEM FOR AUTOMATIC POWER ESTIMATION ADJUSTMENT

摘要

An automatic adjustment system for a variable-speed wind turbine is provided, having a power vector generator for generating a power vector (Pvec) of wind turbine output power; a mapping unit for establishing relationships (βvec, ωvec) between wind turbine output power and rotational speed and pitch angle on the basis of the power vector (Pvec) and an operational trajectory of the wind turbine; a wind speed estimator for estimating a wind speed (vest); an available power calculator for calculating the available power (Pest) of the wind turbine on the basis of the estimated wind speed (vest) and the established relationships (βvec, ωvec). A method of performing automatic analysis of a wind turbine configuration, a computer program product for carrying out the steps of such a method, and a wind turbine having such an automatic adjustment system are also provided.
