Abstract

A wind turbine comprising: a rotor having multiple blades mounted on a hub; microinertial measurement units (MIMUs) mounted on each of the multiple blades to acquire parameter signals of the multiple blades; and a control system comprising: a wind speed calculation unit for calculating wind speeds at the multiple blades based at least on the acquired parameter signals; a wind shear calculation unit for calculating a characteristic height exponent based at least on the calculated wind speeds; a blade angle compensation command calculation unit for calculating blade angle compensation commands for the multiple blades based at least on the calculated characteristic height exponent; and a blade angle control unit for adjusting the blade angles of the multiple blades based on the calculated blade angle compensation commands.
