Method For Estimating The Magnetization Level Of One Or More Permanent Magnets Established In One Or More Permanent Magnet Rotors Of A Wind Turbine Generator And Wind Turbine

摘要

A method for estimating the magnetization level of one or more permanent magnets established in one or more permanent magnet rotors of a wind turbine generator includes the steps of: establishing one or more magnetization sensors at the stator of the generator, connecting the one or more magnetization sensors to a measuring mechanism, processing measured data in the measuring mechanism, and establishing values of magnetization. Furthermore the invention also relates to a wind turbine.
