Claim of US Patent No. 10,767,633

1. A method comprising:receiving one or more first signals from a first wireless sensor attached to a blade of a wind turbine;
determining a first angle based on the one or more first signals;
receiving one or more second signals from a second wireless sensor attached to the blade and spaced apart from said first wireless sensor by a predetermined distance;
determining a second angle based on the one or more second signals;
determining a dynamic twist of said blade based on said first angle, said second angle and said predetermined distance;
determining a torsional load acting on the blade based on the dynamic twist; and
controlling the wind turbine to control one or more loads experienced by the blade based on the torsional load.
